u pointed out itachi not sick hence he has unfair advantage with his holy relics , weapons.take out those weapons then i think its a draw match between MS itachi and MS sasuke.Itachi-not an edo but not sick
Sasuke-full chakra.
and i also remembered itachi actually posses shi sui's eye so he can kotoamatsukami sasuke and make him forget all his techniques and even make sasuke himself a gay. lolz:izuna:
