For my part Unity is the first time I have an UI that doesn't make me swear and wish I was back to using my old Amiga....
I installed Ubuntu 12.04 with the intention of ripping out Unity for a tiling window manager, but gave it a day or so, and that was enough to realize that with minimal adjustment to keybindings etc., it was pretty much exactly what I wanted with the exception of the loss of spatial file browsing which still annoys me,but then again I rarely use use the gui for finding files so it's something I can live with.
