I think if you've got both Greatest Hits CDs, plus the accompanying B-sides, you'll be pretty well covered. As others have said, Zooropa is ok, but Pop never really "blew my skirt up," so to speak. To me--and I know every U2
fan has a different opinion on this--the three "peaks" of U2
's achievement to date are Joshua Tree, Achtung Baby, and ATYCLB.
