Can't get a fag paper between them in terms of ability/creativity, both massively important in their genre. However, I can't forgive Squire for getting (an alleged) big coke habit and pretending to be re-making Led Zep 2 on the Roses second album. Johnny Mar is the winner for my money.
Now then, I think Mark Day formerly of Happy Mondays is a really underrated guitarist. What do the rest of you think?
