I'd say Jiraiya takes it with experience and versatility being his main advantages.

Also, remember that Jiraiya can't just keep absorbing NE forever. If he absorbs NE when he's too low on chakra, he won't have enough of his own chakra to balance into Sage Chakra. And will in turn get petrified.

But I still think Jiraiya wins, he can hold Sage Mode for longer than Naruto anyways.
