Both have reached Godly heights in success pop music has to offer, but who do you think had it better?
Commercially:
Albums
Singles
Tours:
Madonna has 3-4 tours to cross the +100 million mark
MJ's "bad" tour broke Guinness world records in highest attendance and gross in 1987 and didn't have the advantage when touring really took of in the 00s
Critical acclaim: Both are on RS's immortals list, both inducted in the Rock 'n Roll hall of fame, both have several albums and singles to make the best of all time lists.
Impact: This needs a whole thread
Longevity: Madonna > MJ
Respect: arguably MJ > Madonna.
