You're talking about a subjective experience as if it's something that can be objectively measured. I find it the other way around. I've used Macs since the 80's, but lately I hardly touch them, in part because I think the desktop experience is so much worse than GNOME, KDE, Unity, or even XFCE. GNOME 3 in perticular is the best arranged desktop in my opinion because the way it separates the desktop and application launcher/switcher/search into two distinct modes and makes context switching so easy with just a key press, a click, or a hot corner. Everything is always in the same place and easy to access with little cognitive overhead. Whereas using the Mac application bar is really messy, trying to follow flyout menus that go off at odd angles, etc., and that's far from the only reason I dislike the UI. GNOME follows the way my mind works. I'm either using the applications I want or switching between them, and unifying everything in these categories makes so much sense, I'm surprised everyone doesn't follow the model. That's entirely my opinion, and I tend to be biased and think the only reason people complain about the desktop experience is because it's not whatever they're used to, but the only thing I know for sure is that there's no one way to arrange a desktop that appeals to everyone.
