I always laugh how you tend to support Madara and yet go against his wordsNone of the Hokages can match up to current Juubi with Obito and Madara on it, and if they (Obito) becomes the Jinchuuriki then he will be on Rikudou's level, same goes to Madara if he becomes. Doubt Obito will kill himself for Madara's sake, so it will be him for sure
