This question seems misplaced considering U2 is built around mostly electric guitars. So obviously U2 would "rock harder". But I don't think there's any question that, pound for pound, Dave Matthews Band are more talented musicians. Some fans around here seem to be a little threatened by that fact. But I've played guitar for many years now and believe me, the stuff Dave Matthews comes up with is much more complex and intricate than what the Edge comes up with. And Dave Matthews himself isn't even the best musician in the band. Now having said that, I think U2 probably have a better chemistry and make up the better overall band. Too many people on here are just so childish though. Just because U2 is your favorite band, doesn't mean that no other bands are good.
