@actionmanrandell The databook says pretty clearly that only Hagoromo can give Six Paths Sage Mode(the one Naruto uses). Obito and Madara got access to Six Paths Senjutsu by becoming Ten-Tails jinchūriki through use of Six Paths Ten-Tails Coffin Seal. While both ways allows the use of Six Paths Senjutsu, they are still different.

I suggest you actually read the articles.
