Sasuke wins with mid-high difficulty. The Sasuke that fought Bee did not completely recover from his previous battle with Itachi nor could he use his MS to its fullest extent. He only used it for a useless MS genjutsu that he had no mastery over which caused him a lot of pain. He had no knowledge on Bee and his abilities as a perfect jinchuriki. Sasuke used amaterasu at the end of his fight when Killer Bee transformed into the Hachibi. Pretty sure now that Bee has knowledge he won't do this again.
As for people who say that Bee has got nothing on susanoo. Wrong he has samehada which IMO could absorb it. Still it would take time to absorb it and Sasuke can regenerate it. He will lose a lot of chakra in this battle though but I see him killing Bee with susanoo arrows and amaterasu/enton even if the chakra shroud and Bee's speed makes this somewhat difficult.
I would say Bee.
Amaterasu---Bee goes into Cloak mode, pretty sure that makes him fast enough to dodge it.
Sharingan Genjutsu---Gyuki(8 Tails) can snap Bee out of it
Susanoo---TBB, Tailed Beast Shockwave, the tornado move.
People are forgetting Samehada as well. I'm pretty sure it would render Susanoo useless by absorbing the chakra, if it can absorb tailed beast chakra I'm sure it can absorb Susanoo's chakra too. Killer in V2 mode will cause a lot of problems for Sasuke and dodge most of Sasuke's attacks in this form. In full 8 tails mode although his tailed beast bomb would fodderise Susanoo, he's too big. This makes him an easy target for Amaterasu.
I wonder in Samehada can absorb the black flames????
It's too close to call for me. If Sahmehada can absorb Susanoo then Killer Bee will win because his taijutsu and speed is superior to Sasuke's. Amaterasu won't work on him again either.
If Samehada is usless against Susanoo then Sasuke will overwhelm Killer Bee and win. Although tailed beast ball will do lots of damage I'm guessing Amaterasu can be used faster than bee can unleash tailed beast bomb. And full 8 tails ain't avoiding that. Killer Bee's best bet is to not go full 8 tails, V2 max in order to maintain high speeds. While Sasuke's best bet is to utilize flame control to the best of his abilities to prevent Killer Bee touching him.
