I had a good think about what MS Sasuke can do. The Susano arrows, Susano itself, Amaterasu, the analytic skills. Even if Sasori switches bodies, MS Sasuke will figure out his secret and after then, it is not difficult to kill Sasori, much like Chiyo did. The thing that really seperates MS Sasuke and Sasori in tier is the fact that there isn't really anything Sasori can do to harm MS Sasuke mostly because he can't do anything against Susano, and Amaterasu, large scale Susano arrow and the extremely long and large Chidori are things that have proven to cause the 8 Tails, MS Kakashi, the Raikage and Danzo near-death due to their extreme power and speed. MS Sasuke and Sasori play different ball games.
I respect your opinion. I'm just determining whether I think it's true. I actually see how Base Jiraiya is on Sasori, Kakuzu and Diedara's level because they seem to have around the same scope and level of arsenal even though I think he would defeat them, but definitely not with ease. But if I agree with that, then I would have to put MS Sasuke in a league above Base Jiraiya because the way I see it, like somebody previously said, Base Jiraiya is on the level of each of the 5 Kage (except maybe Onoki cos there's a certain underrated deadliness to the particle jutsu) and MS Sasuke is too.
The thing is, the more I think about it, the more abilities of Jiraiya's that I remember and realise are his base abilities and that they have the potential to make a battle of Jiraiya's against Sasori, Kakazu and Diedara more of a mid-high difficulty battle than a high-extremely high difficulty battle and that puts me in the opinion of Base Jiraiya being in a tier above Sasori, Kakuzu and Diedara, like MS Sasuke, and MS Sasuke and Base Jiraiya being in the same tier. But I think to reinforce your post or opinion, you might like to list Base Jiraiya's abilities as they help to make the opinion more convincing.
