I do agree that the B.E.P. are bigger than No Doubt. They do have more hits and did last longer. No Doubt was already struggling to scan Platinum by 2000. The B.E.P. at least had around 8 years of consistent mainstream success (2003 - 2011, and if they release something in the near future, I wouldn't be surprised if it did well so they def could have another successful era under their belt, ND can't).
