Y'know, there are very few people who still actually believe this, after discovering his true intentions, and strength. The Itachi vs Jiraiya debate still occasionally pops up because a lot of readers just thought of that as part of Itachi's act, with Kisame playing along due to Tobi's orders.Remember he had Itachi shaking in his boots who seemingly has sonned Oro since he was a young teen.
I think Kishimoto tried to infer that Naruto surpassed Jiraiya when he confronted Rikudō Pain, but I don't think that actually happened until he was able to control the Kyūbi's chakra.But was he even stronger than Sage Naruto? Naruto was apparently able to master senjutsu and become a perfect or near perfect Sage which Jiraya struggled with. And we saw Naruto one shot several paths.
I'd say that's about right.Idk, I would put him about or a little above Kakashi. He's probably right there with the Third.
