Read the tittle, I think it says "If Sasuke fought Kabuto without Edo-Itachi", meaning the same battlefield, just no Itachi.
But no matter, even if they fought in another location, Sasuke's chances of winning won't raise by much.
Your counter to sound genjutsu wasn't really a counter, even if he can see it coming, he has no way to defend against it, since the attack is too fast, if I remember correctly, it took only one or two panels manga wise to catch them in genjutsu.
Also, there is no proof that Sharingan can break sound genjutsu, if you have any feel free to post them.
About the white rage counter, that again wasn't a counter. You're saying that Sasuke only needs to stream his Chidori, but if he can't maintain Susanoo, you're assuming that he's able to stream his Chidori?
I think it's obvious who would come on top in this fight, any logical person would know that Kabuto is the victor here.
