I love this question. I feel it says a lot about a person. It presents two bands so engrained in culture that they are essentially impossible to ignore.
And another thing I love about this question – there is no wrong answer.
A lot of it depends on what appeals to you: longevity as a band, career album sales, #1 radio singles, cultural impact, melody, songwriting, tough-guy image, et al.
As for me? I’ll take the band that stayed together longer.
