I could never get behind Jiraiya being the "dumb one" like Naruto and Ashura.Ashura and Jiraya were
Correct.
The dude became just as strong as Orochimaru the genius without any handouts or advantages unlike how Naruto or Ashura got to Sasuke and Indra's levels.
Maybe Jiraiya got mad help and handouts off screen, but from what we've seen, Jiraiya was just as naturally talented as Orochimaru, especially considering that he had a pretty demanding hobby which would have cut into training time, eliminating the claim that he trained his ass off 24/7.
Technically speaking, he wouldn't need to, as he would suppress Kurama before the fight.How does Hebi Sasuke tank that again? XD
But I'm not here to debate Naruto vs. Sasuke for the thousandth time.
