I would rather make all these bands try to reach for my level of success
Honestly, I feel Maiden's level of success is the best. They are legends but still maintain a reachable and down to earth persona. Plus them having always sticked to their own brand of style and their level of musicianship also gives them creed. I personlly feel, them going on Ed Force One during Somewhere Back In Time and Bruce's multi-talented personality is just awesome!
Possibly the same can be said about Rush but I'm not super into them or follow them that much.
Really like Led Zeppelin and Aerosmith (the later more) but their members just doesn't click as likeable as the boys from Maiden, even being highly successful or popular.
Gojira also has awesome musicians, though still comparatively a new band but when I saw Joe Duplainter being interviewed at Grammys for their album Fortitude, I felt they are really cool and may go down the line as guys from Maiden. But I'll still go for Maiden.
Motley Crue, though highly praised in their heyday and still being a well known name, went through a life style that may be luring but will be very overwhelming (atleast to me) and enough to turn one highly anxious. While I really like their 80s albums, after that they appear to be more as a brand name than a musical outfit.
Very close second for me would be Metallica. Legends in their own right yet super cool in nature, arguably the biggest name in Metal (somewhat a representative for the genre) and even outside Metal circles. I actually like their interaction with the fans and showing their gears/doing rigs etc. In this case, Maiden as a group is very reserved kind.
