the sage put a ****in moon in the sky and solo the juubi by himself n it was stated that edo madara only had 1 third of the sage power so obito isn't even close
He had Rikudou's power before becoming the Jinchuuriki; Rinnegan, Uchiha and Senju. However he is more connected to the Rikudou now, and I believe as Juubi's Jinchuuriki he can use the Banbutsu Sōzō to create the Infinite Tsukuymi.
