HOHOHOH! Hello children, I was just wondering if you kids think that Madara is near or at the Sages level HOHOHO!
Madara may be weaker than the SO6P at his prime.But,
He sealed Juubi(-1/2Kurama) instantly , SO6P may have worked hard to do so.
Madara have the advantage to be the third guy to have Juubi's power , he has a lot of knowledge of how those things work , he read the story of Hagoromo and worked on it.
with the SO6P's heritage Madara have the potential to become stronger than Hagoromo was at his prime.
With the fruit , he is going to be stronger.
Technically , but what if a "good" will was a lot stronger than a "bad" one.
If it's going to be a fight of "will" (black staff of Naruto or SO6P against black staff of Madara) , the power you have is not significant but the strengh of your will is!
I believe Madara will lose against those 2 , cause he is not stable , his will is not strong.
