Orochimaru wins.

Part 1 Kakashi was weak. constant usage of Sharingan could put him out of commission for days as shown with Zabuza fight. he could only use Chidori, the weaker Raikiri, four times a day before going down.

Part 2 Kakashi had trained to get stronger and he did so. he could maintain use of Sharingan for very long periods without any drawbacks and could use Chidori many times over.

taking that into account, Part 1 Kakashi can barely dish out Kamui even once, and if he somehowd did he would be down for the count. Kamui also requires target to be stationery and smaller or moving in a straight line, something that was even evident in 4th shinobi world war.
