A would easily own sasuke dude... its not even much to think bout to be honest... even when sasuke gets EMS A would still own him!!
I know but people are going to want explination so I gave them one.
First of all, u compared sasuke with susanoo's rib (less than 1/4 of susanoo's powers) to raikage at full power which is wrong bcuz it was sasuke's first time of using it and A isn't better than sasuke at using lightnen(kirin is proof of that)
Even if it was Sasuke's first time of using Susanoo, he had the ability to go full on Suasnoo (I believe). You mean to tell me between the minutes that passed with his fights with the other Kage to Danzo he completly mastered Susanoo? (The whole 5 kage summit battle and Danzo's battle could be aproximated to about 45 minutes in total) I don't believe that. Sasuke had the ability to use full Susanoo but he didn't, which was his mistake. Idc if it was Susanoo's ribcage or not, Sasuke was being an arrogant little punk thinking he could take on the five kage and kill them all. We saw three of the five Kage best him, and if not aided by Gaara, Zetsu, and Madara on each turn, he would've been bested. Now if you want to give Sasuke full Susanoo with his battle against A in this hypothetical then alright, Suasnoo's arrows won't come close to A with his speed, we haven't seen Sasuke's full Suasnoo get hit with a powrful attack so we don't know just how strong it's defense is (It could be just as brittle as his bones were to A. Not saying it is but the power of Suasnoo varies from each user). Sasuke would just as well go blind excerting all that chakra against A attempting to defeat him with Susanoo and Ama when neither can hit him. I'm sure that if A knew that his with his ax kick wouldn't finish Sasuke he wouldn't have gone through with it (just saying) or even if he did he would've just took it like he took his arm burning (and cutting it off like he had a spare in the trunk). I also knew somebody was going to compare Kirin and to that I say, Kirin takes time to activate, and even in that 1/1000 of a second we've seen a reaction time to defend against it (when Itachi activated his Susanoo), who knows if it's possible to evade but with A's reaction speed being being possibly greater then Itachi's if anybody he can (although I'm not making that a definate defense against his jutsu), not to mention you need to be outside for it. I find A's lightning armour to be more affective then Sasuke's jutsu (another thing, Sasuke's Chidori was completly nullified by A's armour so that shows defense power, how much idk. Can it defend against Kirin idk we haven't seen it)
