Neither, I'll go for Orochimaru. He is the only person he deserves that title. Madara is a zombie, Obito only has ties with Kakashi and Juubi can't be a villain.
Orochimaru hasn't really done anything to piss off Naruto apart from swaying Sasuke though
Obito.
This is just Madara's "plan" and that's honestly just about it. Obito was clearly altering Madara's plan aswell, he clearly didn't want to revive him at all.
Obito has been from the start, screwing over his teacher, screwing with Naruto's life, forming Akautski, becoming the mastermind behind the whole Tailed Beast capture project, trolling the whole world into thinking he's Madara, manipulating Nagato, screwing with Sasuke's head and more.
Madara's just some OP guy that hasn't even been here that long that has a boner over Hashirama.

And he did all of that because of who. . . ? hmm
