All the useful menus in windows 11 are buried inside the new ones

That’s UX; not UI

And the not using accent colours is either intentional or a bug; if it is a bug then you can’t blame windows for it, because this side also has it’s fair share of bugs. And windows’ design philosophy isn’t customisablility, but rather ease-of-use, right? (even though it fails a lot at that)

But yeah, Linux can definitely look cooler than windows with a little effort.
