Yea at first i was thinking Itachi becuz he is soooo powerful and intelligent and cool, he sealed Nagato away. But then i analyzed and saw that Pain's powers are INSANITY!The reason itachi is winning is because people let there own bias get in the way i analysed both there powers i just cant see anything that pain cant counter and hit back 10 fold he has tecniques that would end itachi in 1 move and his stamania so much greater so how could itachi win im just being logical
