Not to mention that Naruto must be an author of greater perversion than Jiraiya who is no lia!
I think he's in the process of surpassing them by doing these things (senjutsu and FRS), but he's not there yet because he needs to gain more experience that only time can give him. I would say at this age I think he's more powerful than Jiraiya, but I don't know enough about the fourth other than maybe. Of course Naruto is in debt to each for his rapid development, which is why each generation surpasses the next. Remember Orochimaru said
"Sasuke is better than me at that age and I was a genius." He didn't say "Sasuke is better than me." Orochimaru went head to head with 3 and 4-tailed Naruto, while Sasuke got his ass handed to him by the 8-tails even with MS after the CS was removed. I like Naruto so it's fun to see him come out of no where with bad ass force and surprise. It's easy to overestimate him and Sasuke at first before we see their weaknesses. So in time, no doubt in my mind. If Naruto beats off Pein, than he is a superior fighter than Jiraiya, though not necessarily a superior shinobi yet.
