This is too early to say. And i hate when people say "but Madara is the leader, therefor more powerful" - i seen leaders that arent the strongest, and i seen "founders" of groups/organizations that arent the most powerful.
However, through power-scalling, i would probably say Madara intill we see both go all out. But if Nagato is indeed controlling the six paths of Pain, and if he's>>Pein, then im gonna have to go with Nagato.

Why go through such roundabout measures when he could do it easily and straight forward and only Pein even knew who Tobi was besides Itachi so it wouldn't have been hard.
