I think both bands are amazing and are still great. I think that if Metallicas next album is not as good they may start to shake a little bit as my favorite band. Especially because U2 still makes great albums and Metallica hasnt since 1997. But if Metallicas next album which is coming out soon is better then St Anger (which isnt that good ) than I will be thrilled. I really hope it is. I check the website 94303 times a day for album updates.
Metallica all the way. I ran out many batteries in my walkman listening to the Master of Puppets cassette! Wow...cassettes...I'm feeling old now!
U2 never played anything worth listening to and Bono sucks. 'tallica all the way (up 'till the Black album and/or Napster, take your pick).
really depends on my mood. but probably U2 at the end of the day. if i'm working out or driving tho...METALLICA
