As someone who recently did a switch to get used to Linux, if you're planning on gaming then Nobara is supposedly the beginner friendly gaming distro. I switched to Nobara and my only issue was screen flickering that I fixed by switching from Wayland to X11 (that was as simple a choosing the other option on the login screen). Everything else just works and KDE looks similar to the windows layout so it doesn't feel too unintuitive either.

My two gripes that I can't do anything about are the lack of HDR support (supposedly that's finally in the works) and no Linux support for some online games (The Finals in my case, but maybe if Linux numbers go up they'll finally flip the switch), neither could be solved by having a different distro.

If you just want to game and want it up and running without tinkering too much I recommend Nobara.
