I do my gaming on Bookworm with a handful of extras, and it works very well.

There is a certain group of people who insist that only the distros with the latest packages are good for gaming. Those people are wrong in most cases.

Unless you have a very new GPU (released less than a year ago), your games are not likely to get any benefit from the latest kernel.

Unless your games require the very latest Vulkan features and you run them without Steam, Flatpak, or any other platform that provides its own Mesa, you’re not likely to get any benefit from a distro providing the latest version of it.

Practically everything else that games need is comparable across all the major distros, so choose one that makes you happy, not one that some shill claims is best for gaming. Even Debian Stable, contrary to the undeserved bashing it often gets by a certain kind of gamer, is generally excellent for gaming.
