I don't really like Windows but it's for my gaming PC. My laptop does run linux. I don't know much of anything about 11 and whether it's better or not.
Lutris does pretty much all the main game stores. GOG, Steam, Uplay, EAOrigin, Epic. IIRC they also have custom wine scripts to install with recommended settings so you almost always have the best config out of the box.
There’s also Heroic, which only does GOG and Epic, but is a bit cleaner and easier to use.
