Bazzite is great but gaming is also great on any distro.
Alternatively there are lots of gaming focused distros. Garuda, Chimera, Nobara, etc.
The difference between them will mostly be the “out of box experience”, what software comes pre-installed, and what package manager is used.
I recommended Debian or Ubuntu based distros if you plan to use anything else, as if the dev releases software outside of Flatpak, it’s usually a .deb file.
