im not sure!? lol offensively i think kobe has more moves but mj was stronger/quicker with larger hands. I watched them both growing up at their peaks, mj was guarded by the likes of john starks/jeff hornacek much smaller inferior defenders which allowed him to iso. kobe was guarded by some of the leagues best wing defenders bowen/battier/prince/iggy/lbj but was rewarded by the hand checking rule.
they both boggle my mind with sheer talent/skill vs a superior body ala lbj or 6'9 magic. they are just a mis match every game due to their build + talent.
