Another vote of confidence for CachyOS + KDE! This is my setup and literally the only issue I've had which presented a problem to me is that OpenRGB doesn't like my mobo at all, it's stuck in 'unicorn vomit' mode when I wanted tasteful accent lighting. Games work with minimal farting about, the desktop is great out of the box and customisable in plenty of ways, and it generally treats you like an adult.
