I love both bands and I'm going to see U2 this year ;P

Personally I think that Jon is far better than Bono and Richie is far better than Edge. Tico is also better than Mullen Jr. only Clayton is better than Such/McDonald.
U2 is I think only one band which can record bad/poor/sh*t album and they will win 3 or 5 Grammy for that. Critics love them. Even last sh**t album have GREAT opinions. Jovi always were critics opossite them (after 2000 this changed a little bit) and even great albums like KTF, TD or HAND haven't had good reviews.

Songs - I think both bands have the same amount of great songs but I have some U2 songs which I can't listen and every song from Bon Jovi I can listen (even PBBICowboy which for me is one of their worst song).

Lyrics: Both bands are great.

People: U2 is more popular than Bon Jovi. U2 sold more cd than bj. U2 have more awards ecc. In my opinion they don't deserve for that popularity. They are good but they are not best.

And last. When I hear in TV that U2 will come to us (poland) and how they are GREAT and blah blah blah.... it makes me that I want to sold my ticket but when I turn they live shows on youtube I want to see them right now (and then I'm happy that I have that ticket). I love U2 music and I don't love this U2 which is showing on TV.
