Sasori would be a hard opponent for Minato, especially without info. With info on Sasori's poison and puppets and his heart, I give it to Minato, otherwise I don't know...Though Minato can destroy the 100 puppets in a few seconds (he did it to a whole squad), he has to hit Sasori's original heart. If he can do that, he wins. He can use summons so that can help him too.
i think your forgetting minato doesn't need much info to best someone as he can analyse his opponents techs with in seconds of seeing it
I'd say if Sakura + Chiyo > Sasori
and almost definitely Minato > Sakura (and Chiyo too with some effort)
Then that means Minato > Sasori
hiruko's not that strong.if sakura's punch can smash it rassengan can.
