Sans genjutsu, A wins. The arm eyes means it'll take awhile, and wind vs lightning advantage probably means A'll have some wounds, but A's raw speed and strength means he can handle what Danzo throws at him, and huge chakra reserves means he can go the distance time-wise and then some.
I dunno. My money is actually on Mr. Eyeballs. He does have an elemental advantage and for 11 minutes A'll be unable to touch him. Plus, I don't think A could figure out the secret behind Izanagi.
Regular ol' Sharingan genjutsu doesn't work on him when he's using his Raiton Armor.
I think he'd notice the eyes closing, and could very well come to the same conclusion Sasuke did.

I see Danzo beating him if he tricks Raikage into getting hurt by pretending to be defeated, it's on Danzo's capabilities to hurt him with elemental advantage, unlike Susanoo.
