cliché question, but hey why not?
Arch, Debian, Ubuntu and its derivatives, Manjaro, a bit of NixOS, Tails. I don’t need to explain “Why?” since I don’t use em for personal preference, but more like “when I’m forced to.”.
Arch because it’s rolling release and customizable. I was using Nobara until a couple of weeks ago and switched to Arch because Nobara is basically a tweaked Fedora. The switch had nothing to do with the RedHat thing. It had to do with Fedora’s phasing out of X. I don’t need X for very much, just actually one little game that doesn’t work on Wayland (yet). I think I’m sticking with Arch forever now that I’ve realized how nice it is to not have to upgrade from whatever version number to the next. Gamers who don’t want a lot of hassle and like out-of-the-box functionality should consider Nobara, though. I love it as much as I am enjoying Arch.
I have to use Redhat/Fedora at work, so hate to use them in any personal capacity, hence I mostly use debian or ubuntu based distros (mint, popos, neon etc.). Mostly cuz I have worked with them for so long and they simply work. However, might move to Manjaro/Endeavouros, cuz found GPU passthrough to be more efficient there.
