I voted AC\DC not because is the better band, but it's the band i know better.
Understand that a pre-teen listening to Thunderstruck with a walkman in the middle of a boring school was amazing. Their Live album was my first rock album, i was what, 12 or 13 or something. That was the reason.
I can't debate each band, and like Flash said, those criterias depends on personal tastes, and there are in my opinion other type of criteria, like a particular memory of one band or member, for instance.
Nobody can take out emotion of music, and sometimes emotion is more important than technical ability.
So if this is a World Cup, imagine Angus scored at the 90th minute and Rush is calling it off-side.
