@patricos @mrfoxh Tl;dr it's user priority. Users with high end hardware usually want quicker updates. Also getting a distro that starts closer to what you want should be how you're looking.
It's partly a matter of "Get the OS that's closest to what you want your computer to be", and partly update frequency.
If you're setting up what will essentially be a home console, Bazzite wins. It is a distro meant to feel like the steam deck. If you want something more general, then Mint will do you fine.
If you have higher end hardware (like my old room mate whose graphics card cost more than my entire setup twice over), update frequency is going to matter more. You're probably the one who's aiming for triple digit FPS out of your AAA games, and the way to do that is with up to date drivers. Mint (and other static release distros) tend to release packages a bit after they've been released by the devs, for stability reasons. Rolling release distros typically don't, which means you'll get driver updates, new features, fixes, and indeed bugs, quicker, which means higher performance. If you're like me with a PC that could be in second grade, that's not a big deal, but if your hardware is higher end it's a bigger deal.
