I dont know anything of Linux Gaming because nothing works, on my GPU, or whatever, somehow it doesnt work this is probably a WINE thing.
So Proton and all are sometimes working less well as Flatpak, which would stand against Fedora Silverblue/Kinoite and so on. OpenSuse doesnt care about KDE so microOS KDE will always be buggy it seems.
I use Kinoite and will probably never switch. Its pretty great, up to date, secure, with rollback...
