Darui takes this mid difficulty. Give Kakashi Sharingan and Darui still wins high difficulty.
I think they are equal in therms of power now kakashi has lost his sharingan, but kakashi showed to be the more tactical one.
How would darui take him out mid diff ?
Kakashi wins. More ninjutsu, high level speed, Gai level taijutsu, more trickery(with elemental clones and so on) gives him the win
Gai level taijutsu
MS Kakashi was stronger than Darui. Not 3 tomoe.
Darui is slightly faster and has greater chakra reserves. Their fight speed is equal but when it comes to movement speed, Darui takes the cake but not by a huge margin. You wouldn't be able to tell the difference though until those crucial moments in a fight between them, like who can close distance faster between the two to attack with their lightning-infused kunai/sword or who can dodge an attack and successfully land a counter attack faster.
Darui can win by shooting Kakashi down with his Laser Circus and it won't be highly difficult considering its range and precision mechanics (it will follow him).
He used to fight Gai in taijutsu battles very often and in their only FB when they were younger, he ended up as the winner, so it's safe to assume they are relatively close. Obviously i'm not counting upper-echellon of gates hereYou must be registered for see images
