I remember he made a cage out of thin air to put hinata inOk. That's why One Eye SM Madara was powerful. Double SM Madara would have been way more powerful than One Eyed one... In the Databook of the movie it is said that Toneri chakra mode is similar to Naruto's Kyuubi mode in power. If you notice Tenseigan is more about the body unlike the Rinnegan. And that's why it gives a chakra mode. Rinnegan is more an Eye power and Creation power..
