Windows 11 for gaming PC, Windows 10 for work laptop, Mac OS for personal laptop and Fedora for my old laptop. Also using both Ubuntu and Rocky Linux for servers. Steam Deck is still on Steam OS, Pi's use Raspberry Pi OS (aka raspbian). I don't really have a 'main' computer as it mostly depends where I am and what I'm doing.

I'm pretty comfortable with any OS at this point, even on mobile devices (both Android and iOS/iPad OS). I'm not a big fan of Windows but it pays the bills working in IT. I was in the process of migrating servers away from Ubuntu and onto Rocky (rip CentOS) although with the recent changes in Red Hat Land... We'll see how the rest of the migration progresses.

Dual boot Windows 11 and EndeavourOS on KDE

Windows 11, but I'm currently playing around with different Linux distros trying to see if I can finally get rid of windows for good.

Q4OS, a very user-friendly Debian-based OS.

Windows, Linux on my servers and Raspberry Pi machines. Linux on desktop is oh-so-close, but it's been oh-so-close since the early 2000s!

Ubuntu mainly and Windows mainly for streaming. Discord lags for some reason when I stream on Linux. I also have Fedora and Manjaro on my second/third comps but that wasn’t asked..

Arch with i3wm

Windows on desktop, Mac on laptop (altho likely switching to Framework with windows soon)

For everything but VR, Arch Linux with KDE Plasma. For VR, Windows 10

I've played VR on Linux before with my Vive but it's definitely not feature complete yet. I just got Knuckles for it though so I've been using the Vive with them a lot recently, so I might start trying it more often. The lack of desktop view in SteamVR on Linux is really annoying though (I got it to work once, but that was the only thing that worked at the time lol)

Ubuntu at work, Arch at home. Having a linux machine at work has been an incredible upgrade.

KDE Neon. It's Ubuntu LTS with the latest KDE development stuff.

I generally dislike Ubuntu because they have some really odd breakages and bad defaults, but Debian just gets too out of date eventually. I do use Debian for anything that needs Linux and isn't my main desktop, though (and *BSD if it just needs UNIX).

Win11 on bare metal (for games) with VMware workstation running Silverblue and Arch in distrobox. Most of my time is spent in VMs when not gaming. Did the dual boot thing for a while but it got annoying.

Arch with KDE on my desktop where I play games and fuck around, Manjaro KDE on my work laptop, Debian on my servers. Doesn't get much better than that.

Windows.. for gaming on my desktop and Photoshop on my laptop.. I know there's alternatives, but not without compromise

Windows 10 Pro, I'm waiting for end of life in a couple of years to migrate to Linux. Depending on how it goes, it'll probably be a one way trip.

Manjaro, because it's up to date while easy to use.

Ubuntu. For at least a decade now, I'm sure.

Windows 11 as my everyday os

But everything around me is Linux (proxmox running Debian LXC) or BSD (opnsense, truenas)

Windows 10. Would migrate to Linux, but between Adobe software and abusing the personal unlimited backup (specifically not enabled for Linux due to power users) from Backblaze it just makes more sense to stay right now.

Windows 10 enterprise msdn. Unfortunately it looks like eol is pretty soon. I'm not liking windows 11 at all. Surprisingly this time pro and enterprise have the same eol dates, or have I read it wrong. Microsoft usually supports enterprise for a bit longer.

LTSC is to 2027 but I think there maybe some compatibility issues as it's not really designed for being a desktop OS. Might give that a whirl a bit later.

Slackware Linux currently

EndeavourOS on desktop and laptop. It's been working great for years

Windows 10 Home

Windows 10 but I do most of my work in an ubuntu 22.04 VM in virtualbox. But use windows for games and casual use.

Server runs ubuntu 20.04 server which has a bunch of services for my network and my main storage.

Laptop runs ubuntu 22.04 desktop. It's an old laptop so I'm using ubuntu to extend its life.

Windows 11 for my gaming PC. Debian running KDE Plasma for my work PC. Debian without a DE for my various home lab PCs.

Debian 12 with GNOME. I'm boring and just want something that works. :)

Kubuntu FTW

Linux, I like my main boxen to be stable. Unlike my Windows game box.

My partner and I have been on Manjaro for 3 years and never looked back

I use Gentoo because it's quite customizable. What's more, building a whole system from source is more secure😄.

I have dual boot Manjaro/Windows, but honestly I haven't used the windows partition in two years except for the very occasional moment I need to check if a document format is alright to send to someone, or anyone else not familiar with Linux needs to do something.

Debian Unstable on my laptops and desktop, Debian Stable on my server, Windows 10 is dual booted on my desktop for gaming.

Fedora KDE feels like the perfect blend of customization and stability for me. Oh, and the packages are up to date. I have been on Linux since the early 2000's and finally stopped distrohoping with Fedora about 1 year ago.
