And what you're stating is fact? Everything you've said is mere speculation and hyperbole in favor of Itachi and against Kabuto. That's why you need to get a grip.You do realize that what you are creating are mere scenarios? I can create a scenario where Itachi would win but in the end, they will just be scenarios and nothing else. Anyone can create a scenario where their favourite character wins.
What you pointed out did not happen. The paralysis technique only blinds and deafens the opponent, Itachi was able to keep his Susano'o up. 2nd, the attack that just hit Itachi hit him because he protected Sasuke with his Susano'o. Kabuto confirmed this, I am not sure why you don't understand what happened.
Its hilarious how much of a biased review that is.
