This is a community that is only for nerds jk. everyone who doesn't scare when seeing UNIX terminal welcome! rules:
Arch because my installs keep working, and I'm really used to it at this point. In the future I'd be interested in trying something like NixOS/Guix, Silverblue, or Qubes.
The mobile landscape is just a privacy clusterfuck. I flip flop back and forth between Android and iOS a lot. Maybe one day I'll take the Graphene plunge, not sure.
I've always just used ubuntu with i3 because I honestly dont really know what I am potentially missing out on. What is a reason to use something else?
I prefer Debian since Ubuntu is basically just a more bloated version of it.
I use windows because that's where I can play overwatch and fortnite. That's literally the only reason. And photoshop, but krita is almost just as good. If I didn't play games not available on Linux I'd probably use Ubuntu instead. Why? Easy to install, very customizable, better for programming, scriptable.
Arch Linux. It's too convenient. The AUR hosts a massive amount of packages, wiki is super detailed and covers solutions for all sorts of edge cases. Needs a bit of tinkering to get started but once things are set up it's very stable, and still gives you a lot of freedom to tinker with your system however you want. The only other option I've considered is NixOS which has some pretty interesting features
I'm mainly using Fedora these days, but for some games I still have to dualboot Windows, which I can't say I'm enjoying. Just over an hour ago the Nvidia drivers crashed. On Windows. Repeatetly.
Anyway, I'm quite happy with Fedora but I haven't tried many OS to be honest. I prefer stability over the slight advantages other OS might have
MacOS for work and most things, Windows for gaming. After years of distro hopping I am now enlightened, free stuff is free for a reason.
SteamOS on my Steam Deck is great though, and gives me hope for the future of Linux gaming, but it's not here just yet.
