Lol, the onliest deficit on Madara is he lost 2 times. 1 Time with a Demon vs the 1st Hokage. And 1 Time with the Nine-Tailed-Fox (whatever you call it) vs Yondaime 4th Hokage. But still his Sharingan owns and he's in the body of the best friend of Kakashi.
So Nagato got Rinnegan, should be the best Eye they've said, but I guess they won't ever fight against each other. Since he's just a marionette, Madara will loose again vs Konoha. It's Fate for him not to win, althought he got the strongest shit. He always tried to use people and still lost. That's pathetic, isn't it?
In my opinion I would say Kakashi would own them if he were a(n) Uchiha, and had more Chakra, because he's not a(n) Uchiha. Just criticize me plox if you mean I am wrong, I am interested in your opionions.
