Orochimaru is a master of substitution jutsu's. If Kakashi wastes his Kamui on a substitution then he's going to be severely limited due to the massive drain kamui has on his chakra reserves. Also Kamui itself seems to only be effective against objects that aren't moving around much or are moving in a straight predictable line. This was made evident when he only managed to Kamui off one of Deidara's arms and Deidara wasn't even looking his way and had no way of knowing Kakashi could use such a jutsu.

Orochimaru is far more powerful than Kakashi. This is evident from how badly Kakashi crapped himself during the Chuunin and exam and from the fact that Orochimaru is one of the Sannin. Kakashi also struggled greatly against an incredibly worn out Sasuke that had just spent most of his chakra fighting off Danzo. Sarutobi himself stated that if Orochimaru took him down then there was no one else in the village who could match up to him during the Shukaku arc.Kakashi couldn't beat Itachi who beat Orochimaru. Therefore,Orochimaru wins this battle.
