I have never used bazzite to give you an honest answer to that.
all I can say is that I was distro hopping for a good while after running into roadblocks on ubuntu, and Nobara is just where everything clicked into place with usability, and ease of gaming.
I mean, base Fedora probably is more stable.
Playing games requires an lot of extra stuff, and the kernal is more bleeding edge in nobara to keep those GPU updates (if AMD) and performance tweaks fresh and useful.
but generally speaking from my experience, Nobara is no more or less stable than anything else, windows or linux. And any issue I did rarely had was typically resolved with a reboot, and generally from a game.
