Yes I do. Overall, Orochimaru is on a whole another level compared to Jiraya. The only thing posing a threat would be Frog Genjutsu, but sadly the location is not J-man vs Pain and Orochimaru can simply Fuuton them up and make frogs useless for the rest of the fight.
Orochimaru has at least 3 ways of poisoning Jiraya, is superior in speed. They both canonically fought many times and Jiraya lost evey single time to Orochimaru. He has no way around Oro's regeneration, especially in his 8branches form which is regeneration itself.
Orochimaru also has tons of defensive/mobility/mitigation techniques so at the very end, he can easily exchange hits with Jiraya, which is something J-man can't do
I don't feel like writing a very long post, but there's much more to it. Orochimaru was portrayed as a stronger one out of them and it was proved in manga.
