People who saids Kakashi has more exp then Darui. *black guy slang* --->Where you get that at? Your logic is that since kakashi is a genius, has sharingan, blah blah blah he has more exp then Darui. We know almost nothing about Darui's background (Unless you read wiki or you're Kishi's secret assitant), so saying he has more or less is preety crazy.
From where I see it Kakashi has sharingan and Kumai and the infamous 1000 justus. Since (Kakashi) tendencies are never shown to go for the kill with kumai BASED off the manga. I would think he wins just from the variety of justus.
What Darui has over Kakashi is stamina, chakra, and black lighting (Who knows if sharingan can copy it, I doubt it can). Both are experts in there own affinity lighting. But I would side more with Darui because Kakashi only use lighting as rakiri (his equilvalent of chidori). And my guess and probably everyone else's guess is black lightning is stronger than normal but its base prob isn't stronger than Kirin.
If we run down the list that Kakashi fought in the past (We don't know who Darui fought, see where I'm coming from?) I think Darui would win those battles easier than Kakashi because kakashi's stamina is crappy.Now if we reverse that with who they recently fought, Kakashi vs the Silver brothers I think he would get raped due to his stamina and chakra. We don't know how well kakashi did with the 7 swordsmen so I'm guessing he won that too with help.
So either side can win much less draw. Saying that "Kakashi, no contest" wtf? Who saids that. There should be more draws than wins and losses in this particular thread because they are possibly the most even MU ever with little known on Darui.
