I'll second that extensions bit. The difference between Gnome and Unity is that if there's something you don't like about the former, you can install an extension to fix it. If there isn't an extension, you can write one - at least theoretically. Anecdotally, that sort of shifts the blame for missing functionality around. It's no longer "my wm is missing x" it's "I haven't written x for my wm yet."
