The only users with the power of the paths were Hagoromo and anyone using Madara's eyes, both had the same design. The users of Juubi's Rinnegan eye (Juubi, Madara and Kaguya) could cast Infinite Tsukyomi, what might explain why Obito tried to use it only through the Juubi's tree form while Madara could cast it by himself. And Sasuke is the only one who used the Space-Time flash step.
