A more appropriate comparison would be Dido V Coldplay. Whose music do you prefer to put your Ikea furniture together to?
That's my point. Everyone is entitled to their opinions, and you can certainly dismiss a band based upon on your own personal perception of their music, or what it elicits. However, that does not change the impact or popularity that a band has a with a world populace, or specific generations of people.
When comparing U2 and Coldplay, it's not an issue of whose music is more masculine, or whose is more bland. Countless people my age view Coldplay's music as exciting, and U2's music as weak, overblown, dinosaur rock. By the same token, my parents would say that Coldplay are a bunch of *****whipped Wa***rs who make awful music.
I do not ascribe to either of those views, but there's certainly a contrast that exists
