I grew up listening to Sublime, living near Long Beach and so, this album gets my vote for nostalgic reasons. It's catchy, but of course, more commercial sounding, especially when "What I Got" (both versions), "Santeria" and "Wrong Way" get massive radio overplay, especially on KROQ (but I stopped listening to KROQ in full in 2000 and so I'm assuming they get overplayed). 40 Oz. was a better album, more diverse, and has more staying power. Robbin' The Hood is an underrated album too, which seems more geared to the Southern California underground if anything, but has some gems in there. These days, Sublime's audience seems to be anyone and everyone on the college scene, as the band is honored much in the same way that Nirvana is post Kurt-Cobain...just because the late Brad Nowell was a Cobain-type figure in some respects.
I never really liked Def Leppard and so, I'd vote Sublime here easily.
