Yet Bee took on and would have killed Sasuke 3 times with his MS.. hmmmmm YEA.!!! Bee showed him what is Kage level is all about. Plus Kirin was his desperate move to try to beat Itachi who was sick and dying. The fight was practically given to him.Base sharingan user can be consider kage level and suitable to be hokages.
Kakashi have only Halve on the uchiha eyes and he was well known for copying 1000 jutsu.Kakashi have almost all the element jutsu because of the sharingan.
base Sasuke take down dediara and orichimaru ,who were consider to be very powerful.Sasuke was even strong enough to take on itachi with kirin.
Itachi did take down Kureani and kakahi with base sharingan
He beat a sick Orochimaru and a ninja who his brother beat without even making a move. Plus you can't compare him to Kakashi because Kakashi's genius in skill and strategy is on a whole other level than what Sasuke is on. He has power but there has not been genius on a strategy level without using a Genjutsu.
