Fedora. Switched to Linux full time over a year ago, after years and years and years (like... 06/07?) of dabbling. It blows my mind how polished and wonderful it is to use. It's completely everything I need, and it always blows my mind that it's fucking free
My computer isn't good enough for gaming, but I use the steam deck for that. I'm accidently 100% Linux (well, and android, which doesn't really count). Lol. But, man, I was nervous about making the switch to completely Linux. The only time I'd done that before was back in like 09 when I had this shitty Acer laptop that I swapped to Ubuntu because it simply would not run windows. That wasn't a great experience, but things weren't as polished then, plus it was the world's worst laptop. Now I feel like I've upgraded to something that should cost 5 times the price. Like, it feels like I should be embarrassed by how good it is, like it was a splurge or an irresponsible financial decision. And it's free!
There are some games that run anti-cheat that just don't run. I don't play any of those at the moment, but other than that, no.
The odd thing has quirks, but between Steam and Lutris, I'm good. Not a heavy duty gamer though.
Fedora is awesome. I use the immutable version Kinoite, and it's fork with non-free extras Aurora. Dev container is with Arch just because there are a ton of packages. All the GUI apps from Flathub.
I need to add KDE to this mix. What a wonderful desktop it is. Like what Windows should be but is not.
I'm running Bazzite right now, because I wanted to test it out, but normally I run Silverblue. When I first went to Linux years ago it was all Ubuntu, so I got used to GNOME and unity. Since then, I've never really been able to get into KDE. It feels too windowsy to me, and I fell in love with the quick keyboard controls and the smoothness on gnome. I fully get why someone might not like it, but for me it's a near perfect fit.
That's honestly the best thing about Linux. With windows or Mac you're stuck with how they want things to function. I love being able to change my DE, even if I never do it
I also didn't like it for years. I used a tiling window manager (first i3, then sway), but tried the new plasma 6 and really liked it. Dolphin file manager was the thing that converted me.
