I've been on arch with swaywm for about 3 years now, have't really had to tinker with it at all after getting everything set up. Mesa drivers with amd cards are awesome. Biggest issues I've had were not with gaming but with proprietary codecs in firefox or getting MS Teams to play nice for work. Other than that once in a blue moon the gpg keys for pacman may need to be updated before running the regular update command. I don't recommend sway for everyone, i just find it convenient for me, gnome or kde is fine too.
