Lets look at this guys: Are we all forgetting that naruto can increase the power of his new six paths mode by just absorbing nature energy?
Naruto faced sasuke who absorbed all the tailed beasts with his kekkei mora and made an even powerful susano'o. All naruto did was increase his chakra by absorbing more nature energy in which he formed the three headed nine tails and used its power to counter the full and final strike of the tailed beast susano'o. Even kurama said that the way in which sasuke combined all the split chakras into one was better than that of the six paths. Equally, I say sasuke reached the level of the six paths during his final fight with naruto and naruto still countered it with only few of the kyubis chakra to spare in which saasuke had to absorb to do his enton-chidori move.
Gentlemen, keep calm, naruto is stronger than madara.
1. He's more tenacious than madara
2. Dont forget that the techniques madara had to rely on to fight in his rikudo mode are all powers naruto posesses as he is the sage and light god
3. HE IS F***ING NARUTO.
