even after madara got both rennigan, he wasn't anything too special. chibaku tensie, no problem, they are destroyed neg diff. shinra tensie, 6 tails naruto tanked it, next. animal path, next. limbo, useless against naruto. naruto's senjutsu of the six paths is a better more unique version of the two. he has access to the bijuu's abilities. he is able to, for the most part, solo kaguya. when naruto and sasuke were fighting madara, he was getting wrecked. he lioterally did nothing to them in that fight. unless he does infinite tsukiyomi, which i highly doubt naruto would give him the chance to fly high into the sky to activate it. also, madara did seem like he was getting sealed by the magnet seal before he switched with his limbo. also, madara can be killed the imortality thing was hyperbole. or naruto could just take the bijuu from him. a week obito was able to wrestle chakra from the 8 and 1 tails from him. naruto can take a lot more easily.
