Madara stated that the SO6P managed to stop the juubi in his era, presently the juubi is controlled by a jinchuuriki and logically, one can say that the jin. of the juubi is expected to be even more powerful that the SO6P, cause he only took a part of his power and not the full thing. Due to story plot, I can assume that juubito is on the same level as the SO6P except that he's not mastered the rinnegan and the powers of the juubi, but in terms of amount of chakra, and quality of chakra, i say the juubi surpasses the SO6P and so its jin. This is just like trying to compare, in terms of the kyuubi's power Naruto in full BM with the full Kurama(yin and yang) ands Kinkaku and Ginkaku or their offsprings. A copy can never be as good as its original in the same state. I say if there were two personalities with the same knowledge and intelligence as the SO6P, one born as Hagoromo Ootsutsuki(with chakra) and the other became the juubi's jin, there's no way Hagoromo could defeat the juubi's jin. So stop the endless blabbing of the SO6P being able to take out the juubi's jin and everyone else in NV.
