I think this one would end in a draw. Sasuke was able to cut one of the 8-tails tentacle pretty easily, Ay should be able to do something similar. The TBB would be a problem, but since the Raikage was able to dogde Amaterasu, which is supposed to work instantly, I think he should be able to dodge the TBB. I think Bees swords would be useless against Ay IF Bee wouldn't be wielding Samehada, which would help Bee a great deal in this fight. It pretty much all comes down to how fast Bee can wield Samehada, if he's fast enough to dodge Ays attacks, and then drain his chakra, the match is his, however, if Ay can get past Samehada, I think he should be able to win.
