I think Zorin's approach makes sense for people who don't want to learn a new interface and don't have a lot of technical experience. GNOME does generally already have a good interface, but I think a lot of non-technical people wouldn't understand (or want to understand) stuff like shell extensions and GNOME tweaks.
I don't think I would switch to it anytime soon, but I could imagine it being used in a university.
