It will be a tough decision.... But I will go by Kakashi, he was the only one skilled enough to be becoming Hokage, I will give these Instances: Sealing the Curse Mark: Even Orochimaru was impressed that he could do it (Naruto Episodes) The Tskyomi : He can also teleport things through dimensions Chidori: He invented that techinque, and which later became Sasuke's Main weapon Half Sharingan: He has the Sharingan in just one eye and he was able to perfect as many Jutsu's, what if he has the full sharingan and he has the Bllodline Limit. Let's face the truth, Sasuke is who he is because he relied on other people strength and the Bloodline Limit, which is still an advantage. Though he is also good tactically (His fight against Deidera shows that) but he is still not yet in Kakashi's League. If Kakashi is an Uchiha, he would have been better than Shiuhi, Madara and Itachi and this is the Only problem he has also, he doesn't beleive he can defeat an Uchiha. So My Vote still goes for KAKASHI, The Copy Ninja. Even the fourth Hokage Acknowledge him
