@GIRUGAMESH: My point still stands, Sasuke wont use PS at start unless he has no choice. The fact that hes Susanoo was easily affected by Mei steam proves that it can melt from temperature and it can also be broken with enough force applied this was also shown with Madaras Susanoo. Grimmjows casual Cero had enough temperature caused by friction to reduce a Hollow into ash in under a second which would be lethal to Sasukes complete Susanoo. Sasuke does take this with Genjutsu but I want to know for sure how Killer Bee broke free from Genjutsu?
No, sorry but your point doesn't stand, my link (leading to the pic) disproves it. As seen against the Zetsus, Sasuke will not always go for his complete susano as a last resort, and may well go straight for it.
And your power scalings are...confusing, to say the least. Grimmjow can destroy a hollow, so he can also obliterate Sasuke's PS? Where are you getting this from? If Grimmjow was able to hit Sasuke with a cero head-on then yes, he's done for, but as long as he has susano in one of its later stages active then he should be fine.
Please remember that Itachi's incomplete susano was hit by this:
(Pirate site link removed)
And he still survived.
As for Mei and the other kages, yeah, susano can be broken with enough power, but I've never seen anything from Grimmjow that could one-shot Sasuke's PS, or even come close to it. In case you hadn't realised, Sasuke's PS>>the one he had at the kage summit.
Sasuke wins this with or without genjutsu, amaterasu, PS and the combinations of the two will be enough to take this. It will be tough, but Sasuke will be the one walking out of this.
