Wine, DXVK, and other compatibility aids have made gaming a relatively trouble-free experience. Most of the time, if you use Steam, you can just click play and your game will work out of the box with Proton. Performance hit is usually not a big deal, and some games even perform better on Linux. Some games I play also have decent native ports. Outside of edge-cases, the only issues tend to be games with aggressive DRM or anti-cheat, which is hard to get around (though the situation is getting somewhat better with some forms of anti-cheat starting to be Linux/Proton-compatible). Though, personally, most of the games I play are at least a few years old, and most of the new games I play are indie, so I can’t exactly attest to the performance of new AAA games. I tend to hear they work well, outside of the previously mentioned issues, however.
From what I remember, AOSC OS is fairly easy to install, though it’s more niche, so I don’t know if I’d recommend it to a new user. There’s also Solus, I suppose, but while there is a new release out, I wouldn’t count on it remaining actively supported, given its track record. OpenMandriva and Mageia are worth noting, too. Their parent distro was corporate, but it doesn’t matter since its dead now. Not a lot else I can think of.
