Kakashi is a very powerfull shinobi, he can solo almost all the narutoverse with his recent feats, but exactly obito is the one that he can't kamui, so no, obito > kakashi
to be clear if your talking about a normal battle obito wins but if you take ms away then kakashi wins, note obito has the 7th path in that one eye so be probs does not have the other 6
no simply obito has bounds more chakra than kakashi.....so kakashi would lose.....but if the ms took less chakra or kakashi had more chakra then he could probably beat obito
Obito wins, everyone's argument for Kakashi soloing everyone in narutoverse is Kamui....well that's exactly what he can't do to Obito. And the more he tries to use it, the faster he runs out of chakra.
Obito is a Rikudō who can use Mokuton or rip out Kakashi's soul by simply using Ningendō. The latter is still stronger even without the Mangekyō Sharingan.
i don't know about about that being a factor anymore because kakashi was prepared when he saw the jinjuriki's had Rinnegan. chapter 567 page 12 gai states that they had made a plan for all of pains abilities ergo: Rinnegan therefore kakashi would be able to contest Rinnegan.
