I have a ROG Ally and a Steam Deck. The Steam Deck experience is miles ahead. Windows is such a limitation on these handheld devices (and dare I say PC gaming in general). SteamOS is the real MVP behind the Steam Deck, it makes everything feel seamless.

The Ally feels like a crappy ASUS launcher stapled on top of an unoptimized Windows desktop, since that's exactly what it is.

Also, the ASUS ROG Ally controls are nowhere near as nice as the Deck's. The Deck sticks feel better. The touchpads allow for mouse control.

Get the Deck.

Steam Deck's secret sauce is the software. Steam Deck's software isn't all OSS yet (it's NOT the same as the publicly available SteamOS), so the alternatives are all running on Windows which... is not good (especially for a handheld).

Honestly, just get a Steam Deck. The "power" differences are just not meaningful at that form factor right now.

I'm not a Linux fan, but even disregarding the OS (SteamOS vs Windows), the fact that most of these "killers" don't come with touch pads of any kind makes them an instant loss. So many PC games use a mouse, I'm not using a fiddly thumbstick in its place.

On paper a lot of these devices beat the Deck. In reality the Deck sits on top and looks down on everyone else.

SteamOS (and Linux gaming in general, thanks to Proton) is absolutely great and has been for at least a year or two now. The reduced overhead and lack of update bullshit honestly makes it better than Windows gaming in every way, IMHO. Getting it running on non-Steam Deck mobile hardware is likely a bit of a chore, though. Frankly I don't even understand why anyone would waste time with the competitors.

You can press the power button on the Deck while in the middle of a game and it'll suspend. Pick it up hours/days later and hit the power button and it'll instantly resume your game. I don't believe the Ally can do that.

Screen is not the best, but everything else is superior. SteamOS is much better than Windows, IMO. Though I don't play multiplayer games and I've read some anticheats don't run on Linux. The only multiplayer game I play from time to time is Fall Guys and it works. Emulators are actually where Linux shines and especially Steam Deck - there's an app called EmuDeck that sets up all the emulators you could think of and makes it work really easily. For Epic and GOG games I use Heroic Games Launcher and it works well, I played Spider-Man and Fall Guys from Epic and most of my library is on GOG.

Still I'm not convinced of Steam OS compared to Windows 11, since I would like to play also Epic games and maybe some emulators

How much time, relatively speaking, do you spend playing multiplayer Epic games? If it's more than 50%, then yeah, SteamOS may not be for you. But if it's less than that, then SteamOS would be a better experience, simply because it was built ground-up for gaming. No Windows Defender slowing down your system unexpectedly, no Windows Updates to hijack your system at the most unexpected times, no other bloatware or nonsense services like Bing/copilot crap or ads in Explorer - just pure gaming. These Windows handhelds you speak of are barely optimized for gaming, the most they do is add a launcher and call it a "gaming console" - you still have to put up with various Windows annoyances, which defeats the point of a dedicated gaming console - you want to be able to just pick it up, turn it on and game - no nonsense. One of the cool things about SteamOS is how reliable the sleep/resume is when you're gaming, which allows you to just pause and game whenever you like. This whole streamlined experience is why people love the Deck.

BTW, SteamOS has no issues running emulators. I can't think of any popular emulator that runs only on Windows, or runs significantly better on Windows.

the screen of the Steam Deck, apparently of lower res

The lower res is actually better because it's a small screen. A higher res on a small screen makes things harder to see, plus with a lower res you get more FPS and a better batter life.

very big hazels (to me looks like the first Nintendo Switch).

It may not look good, but it actually makes it more ergonomic and easier to hold. Check any review of the Deck and you'll see they all praise it's ergonomics, like this one: https://www.windowscentral.com/gaming/pc-gaming/steam-deck-review#section-steam-deck-form-factor-ergonomics-and-gamepad

"Despite its undeniable girth, the Steam Deck's attention to ergonomics makes it an incredibly comfortable device to hold, even during extended gaming sessions"

In fact, read the rest of the article - or any other in-depth review. You'll find that the Steam Deck is a much more polished experience overall compared to the others, and this is thanks to both it's hardware and software.

Steam deck has the community. There's more powerful single card computers than the raspberry pi but the pi has the community so everything works better and for longer. I wouldn't be surprised if the decks support outlives the others not to mention the third party market.

better alternatives. Asus Rog Ally, OneXPlayer, Aya Neo etc…

Don't they all cost double or tripple of the SteamDeck? Call me oldschool, but spending $1000 on a handheld just sounds crazy to me. SteamDeck is already pretty much the max price I'd call acceptable.

The biggest problem for me with the SteamDeck, and why I haven't bought one, is simply its 1280x800 resolution, that might be acceptable for gaming, but it's really no good when you want to read a PDF or do other non-gaming things. Kind of limits it's versatility and is just not a good look when you have the same resolution as a cheap China tablet from five years ago, or a Nintendo Switch for that matter, which itself already felt a little out of date at its launch.

I have a Steam Deck and was considering "upgrading" to something that has more power.

But then I wanted to play Torchlight 2, an action-rpg designed for mouse and keyboard that does not have controller support. I wasn't even going to try it, but saw that Runic Games had an input profile for it. The left stick controls your character like it supporter controllers, but it's all using the mouse. The touchpads work for precise targeting. And I'm able to use all 10 skill buttons using modifier keys and adding the back buttons. Plus I was able to easily adapt this to Diablo 3, a non-steam game without controller support.

If you want to be limited to games designed with controllers in mind, go for one of the alternatives. But if you want to be able to play mouse and keyboard games, there's nothing that competes with the Steam Deck.

You can run Heroic on the steam deck to play Epic

Ally is worse than the steam deck in everything unless it’s plugged in and you’re using a keyboard and mouse, at that point you should get a laptop

Emulators also have no issue

The res is lower so it can play higher demanding games, necessary res scales with screen size, a 1 cm screen doesn’t matter if it’s 10 pixels or 10 million but a 200 cm screen you’d want the 10 million

Rivals might compete but they aren’t big enough to handle volume (you might be waiting a long time)

Also Linux is better than Windows

I feel like windows would seriously hamper the experience, it's terrible on small screens and when you don't have a normal mouse and keyboard to use. It also has a ton of overhead that's going to eat into the more limited CPU and GPU.

I'm also pretty sure you can just dual boot windows on the steam deck if you want to have windows available.

I own Steam Deck and the ROG Ally. Steam Deck is a simpler experience, ROG Ally is more powerful and offers a true desktop experience in a handheld.

I recently picked up a Steam Deck and I can also vouch for it; the device is far more than the sum of its parts and is clearly something Valve was only able to pull off after a decade plus of various software/hardware integration experiments.

SteamOS is the star of the show, and it is both fluid and easy to use while also putting more customization and flexibility at your fingertips than any other game interface I’ve seen. The integration of custom operating system, custom game wrapper tech, and their standardized hardware has produced a device that offers the power and flexibility of PC gaming with a user experience that is getting closer and closer to the “never think about it” ease of use that consoles provide.

It’s not the most powerful; it’s really a 720/800P gaming machine, but games look great at that resolution and you can run a lot of games at comfortably playable frame rates.

I had some doubts after I bought mine when I saw the ROG Ally come out alongside hundreds of “OMG THE STEAM DECK KILLER HAS ARRIVED” videos; but it didn’t take long until I saw a lot of those same content creators return their Ally and come back to the steam deck because although the hardware is slightly more powerful, the user experience end is so much worse than it just wasn’t worth it. Not to mention some serious QC issues with it.

I’ve been a PC gamer for a long time; I think I’ve been active on Steam for 18 years now. The Steam Deck is the best PC Gaming experience I’ve ever had. The hardware is great, the controls (and mapping ability of those controls) are great, the interface is great…everything is just top notch about it. Do I wish it was more powerful? Well that’d be great, and one day it will be. But everything about the experience is so good, I don’t mind some of the drawbacks. It’s encouraged me to get into my backlog of games and genuinely enjoy exploring them again. The Steam Deck just makes it so seamless and easy to play your games.

In fact, I’m getting close to time to build a new PC, and the Steam Deck has really changed my thoughts on it. Seeing how far Proton and SteamOS have come…I just really want Valve to take another shot at the Steam Box. A lot of its shortcomings aren’t issues now, and add in some good Steam Deck integration and have it target 1440P/4K Upscaling, you could create an affordable box that taps into a successful and growing ecosystem. I’d buy one in an instant and just not bother with a new PC build in the years ahead.

That’s how much I genuinely believe that the Steam Deck/SteamOS experience is that good these days!

Steam Deck has better software support than ROG Ally. Also, the latter only sports standard analogs, and SD offers two trackpads (which are great, btw).

On the other hand, ROG has more raw power and a better display. I don’t know anything meaningful about the rest you mentioned.

As for the OS, Linux seems better suited for these kinds of devices. Proton runs almost anything and offers a great experience, and on top off that, you can still use it as a daily PC with the use of peripherals. But I’m probably somewhat biased, as I know and love my SD.

Steam Deck punches way above its weight. But it does so much thanks to its lower resolution. Though in the format 720p isn't bad at all. It's what the switch uses as well.

Skip all the Chinese alternatives, they require far more tweaking / researching than you're fit for (judged solely by this post).

Really I'd break it down to games and game types you want to play. If you want say Genshin Impact then it's a lot easier to go with the ROG Ally. There are other Asian games that also don't play nice with Linux. Multiplayer titles also tend to be finicky with Linux. The ROG Ally is also strong enough to dock to a 1080p screen for titles like Valorant or CSGO. If that is appealing.

If you're playing mainly older games then the deck is the obvious choice, it's a beast when it comes to emulation and has much better battery life in that setting than the ROG Ally. It's also arguably more plug-and-play especially if you play mostly steam games.

Running Windows on the Deck isn't very good, it kills the decks battery advantage and the lower performance becomes more obvious. Same running Linux on the ROG is also missing out on what it's actually good at and Linux won't improve the battery life much.

Like others have said. It’s because steam deck runs steam os that makes it better than the rest. It’s a catered os for the device. It was after I jumped in I realised how robust it is. Every game in integrated works on Linux no issue I even took windows off my desktop pc. Best reason is also community. Steam deck has plenty of online support whereas the other ones are a bit more saturated

Thank you all. This discussion is really helping me making a decision. I even thought that YouTubers are being paid for well advertising all these Chinese alternatives and put the Steam Deck in bad light.

The steam deck has better performance when you set it to low power consumption, but the competitors have better performance when set at higher power consumption. If you play a lot mouse based games, the trackpads are very nice. Emulation works great on the steam deck and it is possible to play epic games (I don't use epic so idk how good it is).
