I'm sure it depends on the games you want to play - competitive games where anti-cheat is a thing, sure, but if you're ideologically against having kernel level anti-cheat then that's not that Linux gaming is bad, it's just that gaming as a whole is bad.

Most single-player stuff I've tried has worked fine on Linux with either Lutris + Wine or Steam + Proton. The only games that haven't are super small indie stuff where I just assume they're coded a little poorly in some way.
