Personally I prefer jellyfin but I'll usually stick Foss where Icabn

Personally I run mint and its just a couple of clicks to get it installed in mint. I tried pop is didn't like it that much and gave me less stability with some of my use cases

Depending on the game tinkering may not be needed. With proton most of my games except like dead by daylight it was install and press play

Tis one of many reasons I run Linux mint
