tl;dr: author got tripped-up over fedora's flatpak repo and having to click once to enable flathub in kinoite.
but Bazzite is also another one that is actually specifically focused on gaming.
its sibling, aurora kde, is the one i nearly went with. in fact i still have it sitting on this pc's twin (have two identical ones, bought before the market went to shit). the flatpak-only environment was giving me constant headaches. i ended up on debian, and it's been an absolute dream. it's great to be back 'home', i haven't had a pure debian desktop in years.
fedora's immutables are nice. just 'not for me' (right now). i'll still suggest and install them for others, though, because for basic tasks and newcomers it's a solid and hard-to-break choice.
