This fight isn't as one-sided as the majority might think. Especially with the exclusion of Snake Summonings, and Kirin (though, he wouldn't get the chance to prep such). There's still the argument of Genjutsu, though that is broken via CM transitioning. Then there's the argument of speed, which is countered due to Kimimaro's KKG, being able to sprout bones from every portion of his body's exterior.
Then there's the argument of Sharingan precog, which is bypassed by Kimimaro's unorthodox fighting style (same way Bee fooled Sasuke's Sharingan with his fighting style). Then it comes down to Chidori Spear... If Sasuke goes into CQC then just uses Chidori Spear in close proximity somewhere fatal eg; cutting off Kimimaro's head, or piercing his heart, Kimimaro will die.
I give it to Hebi Sasuke majority vote. Though, Kimimaro has his chances. Don't sleep on him.
