Objectively it is Aerosmith by a mile. Nearly 31 years non stop, heavy radio, video, album sales, and concert ticket sales . Metallica wasn't really main stream until 1991 but since then they have been relentless( I much prefer them before 1991). I would put Van hagar higher but they haven't been relevant in years. The others get airplay and I'm sure to a lesser extent album sales but just werent together long enough.
