You gotta remember though, Hashirama is the originator of wood style. Even if Madara has it, its only a mild form of it. Let's say Kabuto/Orochimaru game Madara 80% of Hashirama's cells (Theoretically speaking), Hashirama still has 100%. What that means is Madara still isn't as powerful as Hashi in wood style. And wood style being the big trait here, I doubt Madara would win on that spectrum. Then there's the Rinnegan and the Juubi; and that's where Naruto, Sasuke, the ALL of the other Kages, and pretty much everyone that's still alive comes in. Its Madara vs. the strongest ninja in the Naruto universe. There isn't exactly a great chance for him.
