Most people mention PopOS (debian-based) or Bazzite (fedora-based). I switched from Windows to PopOS (because I’m more familiar with debian) a few months ago. However, I just switched over to TuxedoOS. The main reason I migrated away is that PopOS is moving to Cosmic, which is a DE (Desktop Environment) produced by the developers of PopOS. From what I’ve read, Cosmic is in a rough place and I had no interest in using it as I like KDE. My recommendation would be to find a distribution that supports the desktop environment that you want to use right out of the box. I’ve also had no issues with gaming on either PopOS or TuxedoOS.
