That makes sense. I've done both team green and red on linux now, Ubuntu and PopOS. My personal thoughts:
NVidia for compute, hands down, it wins. Any AI or compute, you can't compare. But the drivers are worse and a pain to install, and conflicting versions left and right and it's just hell. PopOS saved me by having all of that set up for me.
AMD GPU drivers are still not great if you're running a non "official" distro, but I eventually got it to work. AMD definitely feels more "stable" over NVidia. Way less fiddling with Steam and games too, most seem to "just work" compared to fiddling with env variables with NVidia.
Pros and cons. Personally, I'm leaning Team Red right now. They're really bringing it. I don't see any reason to spend more on an nvidia card unless you are doing massive compute loads.
I have an nvidia GPU and tried popOS and Nobara and I cannot get games to run at all. Keeps crashing or going to a black screen and the game never actually launches. Definitely going to be going team red next round to get off windows finally
They have a few distros hardcoded in their amdgpu install script. I had to go add pop into a line with debian|ubuntu|pop like that so it wouldn't kick me out of the script.
I played on Linux with NVidia for a few years. Was overall okay-ish but I definitely had issues. Just switched to a 7600XT and it's like putting on glasses when I didn't know I had poor vision. Everything just works, wayland is seamless and smooth in a way X11 just never was, DX12 games run faster than they did on Windows.
