Darui has more stamina than Kakashi and has the edge in elements with black lightning, water, and storm release. However, Kakashi is probably the better strategist and tactician.

Kakashi has the deadlier edge with Kamui in the kekkei genkai department. However, he only has a few uses in his tank. If he misses, he's immediately weakened and could easily fall victim to Darui's storm release, which is capable of tracking its target.

Terrain is also important. If they're fighting on land, Kakashi can make use of the earth to block Darui's fire power. However, if they're fighting on water, Kakashi only has Kamui to warp away Darui's Black Lightning Panther before it electrocutes him. He can't use water to block it. And he can't dive to get away from it. Nor can he jump over it as the Panther will just attack him directly.

Assuming they fight on land, I'd have to give a slight edge to Kakashi due to Kamui and his tactical superiority. However, if he lets the fight drag on Darui will simply outlast and put his ass on blast with storm release.
