well MJ was deffinatly a better dancer for sure lol, but i prefer michael because his legacy was bigger to the music industry then elvis's because MJ lived longer then elvis did
i must say that i never listened very much to mj's music, the bit i know is.. ok. but it will never have the rhythm and the mood of elvis' music, although i must admit that some of jacksons hits certainly must have electrified the masses at live concerts. and since you're taking the discussion out of the musical level i'll add that i don't have much respect left for mickael and his mania of wanting a perfect life and a 'erfect' face^^...
Elvis, MJ and James Brown had good careers. There's a reason behind their nicknames. Elvis had some good songs at the beginning, but like a lot of rockers, became too cheesy and romantic as his career dwindled down. MJ and James Brown did it too, but not to the extent Elvis did.
