I mean I tried Ubuntu couple of years ago as second OS, and tbh UI wise that loses even to windows UI

Yes, windows is a ton of shitty legacy and backwards compatibility, which makes it just... Bad

But I'm not sure if it's familiarity with UI, or UI itself, which just makes it feel better

you can modify the "UI", typically called a Desktop Environment, in whatever way you wish. you can uninstall it and install a different one. you can patch it. tweak it. twist it. bop it. you can make it look like MacOS. you can make it look like any version of Windows that you like. and yes, a lot of people hated the "Unity" shell for Gnome that Ubuntu moved to ca. 2010 (and i _think_ still maintains today).

that said, the DE has absolutely nothing to do with system libraries and packages necessary to run a game.
