I'm Dumb?You just said Sasuke without Uchiha DNA sucks.Well, Naruto without Uzumaki DNA would have the large chakra neccessary to be a Sage, so he would suck more.Uchiha DNA or not, Sasuke was still highly intelligence and highly skilled before he awaken his sharingan.So Sasuke without Uchiha DNA base is Kakashi, Naruto base is well, Base Naruto which is not even top 40.
As for Sage Mode Naruto not being top 20.
