@Rage gtx: You're right. Initially I thought Sasuke's Rinnegan was too OP because of his dimensions ability. However, we've never seen what Hagoromo can do with his rinnegan, apart from summoning the dead. Madara has Limbo, which is one ultra-haxx technique. So far Sasuke hasn't shown anything that can defeat Limbo directly. So we have a lack of Rinnegan feats here to decide whose is superior. In such cases, your solution is indeed the best one i.e. we see what the manga canon says. And the canon says that 2 rinnegans>1 rinnegan. Of course, there's some problem with this logic, as Sasuke's rinnegan is clearly different from at least Madara's. But since Sasuke hasn't been shown to use all the six paths techniques of the rinnegan, we can agree now that Madara's 2 Rinnegans are superior to Sasuke's one rinnegan, for now at least. This conclusion can be overturned if Sasuke is shown to possess all the Six Paths as well as the Outer Path of Madara's Rinnegan. Databook info will also help, as someone here claimed that DB4 says Sasuke's rinnegan possesses all the Rinnegan abilities. If that is true, then the eventual victor would be Sasuke's rinnegan.
