Me personally, my go-to console at this point is the Steam Deck for its sheer versatility. I've got a dock with an 8Bitdo Ultimate Pro connected so it's more or less plug and play. Since building my first PC in high school, I have a huge Steam library. EmuDeck is also amazing so with the exception of a Series X somehow running emulators, the Steam Deck is the best console for emulation.

I've had an Xbox One S as my 4K blu-ray player and have been digging the backwards compatibility, though there's not enough OG Xbox support. I'm more than likely going to mod an OG Xbox with the Stellar chip/HD mod. I've considered a Series X, but unless it can replace my Nvidia Shield TV as an entertainment box, I'll probably stick to my Onse S. I've also considered a PS5, but their games are coming to PC, albeit delayed, so I don't really feel the need to pick one up.

The PS3 is a special beast as those games are seemingly trapped on the console unless ported (RIP Beenox Spider-Man games). When modded you have the ability to software emulate PS2 games (not as good at the launch PS3 but those things won't last), but for me my TV still has a component connection so my cheat is having a PS2.

Nintendo has one of the most beloved library of games, but the Switch does not support much of said library unfortunately. The Wii U on the other hand had better compatibility especially if you modded in GameCube support which runs natively on the console.
