A few days ago I started a thread of top 3 akatsuki battle-smart shinobi. And Sasori took 1st place, while oro and kabuto split for 2nd place. And I said that I will start a VS thread between the first two places. I decided to put oro against sasori because we simply don't know enough about Kabuto. So there you go.
They are both full power, they are both prepared in this fight (sasori has his puppets, oro has his edo tensei). Go for it.
