2. Even Itachi? Itachi is one of the fastest characters in the Manga who doesn't have some sort of godly power up. There is no reason for anyone to take Nagato being able to react to Kirin as fact. Though I do believe he can react...it doesn't really matter considering CST is the only thing that's letting him redirect a giant lightning dragon that can flatten a Mountain.
It's called almighty push for a reason.
He was able to repel FRS and 3 giant toads.
To say only CST can repel it means entering a debate that cannot prove either of us right since you'll have to calculate how strong the Kirin blast is and how strong the CT blast is. The fact is Kirin flattened a mountain and
OBLITERATED ( FRS and Amaterasu aren't just deflected, they literally phase out of existence when CT hits them. They just disappear into thin air, that's how strong CT is- and that was Deva using it, not Nagato, who is much stronger ) and threw 3 giant toads with such a force that literally all of their bones were broken. That's no meh feat.

I guess. But do recall that Sasuke's Kirin was the way it was because Itachi also burned half the battlefield with Amaterasu. Sasuke will have to bust out some serious chakra to make a Kirin the size of the one Itachi did ( when Itachi did he used up most of his chakra and let's not forget that Sasuke ran out of chakra before Itachi did despite Itachi being sick and using the Mangekyou repeatedly ). So I don't see Sasuke managing to make a Kirin the size of the one he used vs Itachi.
I'll agree that Sasuke's PS is stronger than what Nagato has, though it's mostly featless, is it not? The most I recall it doing is cutting off a tree branch which doesn't say much considering Hiruzen and Tobirama did that too, with meh jutsus.
