Either Oro > J-man or Oro = J-man
There's no way Oro < J-man
Itachi literally beat Oro in the space of 10 seconds without even using his MS (his most powerful technique). There's no way Jiraiya can beat Itachi.
Also Itachi only said that to Kisame because he didn't want to fight a Leaf nin because he was a good guy and wanted to protect the Leaf.
And Sasuke has been called a genius so many times I've lost count.
Sasuke is a lot like Madara, the kyuubi said so himself. And he's Madara's little apprentice, Sasuke is being groomed by Madara himself
