I can only speak to PopOS as that’s what I chose when I switched last year. It’s been mostly fine but there have definitely been pain points. If you use a hard drive other than your os install drive then you need to go to the steam website to get the installer and not use the one in the built in app store. Getting mods working for games has been incredibly annoying anytime I have to use protontricks.
Non gaming related I’ve had numerous issues trying to manage permissions for my hard drives. Not sure if this is a Pop issue or general Linux issue.
I second your feelings on bazzite. Last year when I switched to Linux I spent a while researching the best distro for gaming and what I could find pointed to PopOS or Mint. Never even heard of bazzite.
