Maiden. Hands down. Except for when they had Blaze. Paul and Bruce are great. Dave Murray, Janick Gers, and Adrian Smith are jsut amazing guitarists. And Steve HArris is well....my biggest influence as a bassist and in my opinion one of the greatest song writers of all time. He writes pretty much all Maiden songs. They have the coolest album artwork, stage shows are amazing, and while theyre probably one of the most mainstream metal bands of all time theyre still my favorite hands down.
