Both are legends no matter what but I think historically,MAB will be looked at more favourably not just because of the trilogy but also because of the longer career,the way he reinvented himself as a defensive fighter etc etc. Even though I prefer EM,he has gone slightly downhill whereas whenever someone wrote off MAB(countless times)he came back again.However,I think it is so close,wherever you have the name MAB,you must have EM very close by.
