I'm not talking about Jinchuuriki Madara. In the first sentence I was talking about Madara who took Hashirama's SM and is Juubi Jinchuuriki who easily beat Sasuke.
But in the other statement I talked about a normal Madara who has Hashirama's wood techniques but not SM as well as no Juubi. Also I said Sasuke's power given by Hagoromo fades away with the sealing of Kaguya and hence Sasuke will be back to EMS Sasuke with a PS. This is the same condition on Sasuke's side similar to when Madara came to fight Hashirama minus Kyuubi. In that manner Sasuke will get a chance to surpass Prime Madara (though a Mokuton enhanced Madara)
maybe a side effect of the power ups they both got from Hagoromo like they aren't Indra and Ashura anymore after all "their" chakra in sealing Kaguya.
Handling so much power will have some disadvantage. Sasuke is already showing by getting exhausted by two to three uses but naruto isn't means he'll have a major side effect coz of the power up.
