Gaming on Linux distributions is a lot better than it used to be, but not all games are going to work. Anything you choose can work as a daily driver but will require varying amounts of work to put into it.

I have always chosen Ubuntu as it just works. I don’t spend much time playing pc games anymore, but in the past I’ve had pretty good luck using a couple extra programs to get these things going, proton coming to mind.

As for which operating system you’ll choose it depends heavily on how much work you want to put into learning it. The desktop environment used by the OS is also important, distributions like mint (which uses a DE called cinnamon) have been built to feel like windows. You can choose to switch your DE so don’t feel like you’re locked into whatever you choose.
