Im sorry to all of the people who say kakashi could win but honestly get real,
if you think about it logically, sasuke is so obviosly better for many reasons
1. Sharingon-yes kakashi has the sharingon but he doesnt have an uchiha body which is a problem (as stated by itachi and kakahsi himself), Yes he also has the mangakyo but he knows one teqnique which is kamui which is a powerful move but it takes precise aim and it takes an incredble amount of stamina which kakashi doesnt have, Sasuke has Amaterasu, Tsukuyomi
and presumerablly susanoo, and kakashik wouldnt be able to go against that
2. Taijutsu-Sasuke surpassed kakashi (who is a good taijutsu user) a while ago, with more speed and stamina sasuke just wins
3. Genjutsu-obviosly sasuke you cant argue with that
4. experiance- kakashi may have fought longer than sasuke and more battles but how many akatsuki has he taken out(the asura pain body doesnt cut it), Sasuke took out diedara single handely and Itachi(and i know Itachi was going easy on him and was weakened but itachi tried his best so he could get orochimaru out its not like he wasnt trying at all), he even took out a weakend orochimaru which as he was weak is still an incredible feat
5. Lighting jutsu-ok yes raiki is better than chidori but so what, sasuke has much better nature manipulation, but what about Kirin did anyone think about that, That move is virtually impossible to dodge, itachi blocked it with susanoo and still went down,
6. smarts-ok thats the one thing kakashi has on sasuke, he thinks ahead more than sasuke does but sasukes not dumb
It is incredibally obvious sasuke would beat kakashi, maybe not anihilation but sasuke would win
im not being biased in anyway because sasuke does piss me off and i like kakashi but thats the cold truth
