So, who do you think is more stronger, Jiraiya Or Orochimaru?
Both are of the legendary Sannin and each have their own unique abilities.
However, the fact is that the Third Hokage regarded Orochimaru as a more capable ninja than Jiraiya , and believed that Orochimaru was some kind of Prodigy that appear in every few decades.
As for Jiraiya, he was the disciple of the Third Hokage and the master of the Fourth Hokage.
As for a side note,
Orchimaru was defeated in a swift move by Itachi while,
Jiraiya fought hard and was defeated by Pein.
So, who do you think is more stronger?
I believe that Jiraiya was Stronger than Orochimaru, for firstly , he knows the powerful Hermit mode and secondly, he fought supremely against Pein, though he died eventually. Orochimaru may not even dare to face Pein.
