Jiraiya had massive chakra reserves, only short of the uzumaki. Hiruzen had great reserves in his prime but he wasn't known for being able to go 24 hours without a sweat. And it was already stated hiruzen's reserves dropped considerably after he lost his prime. Even hiruzen in his 50s had little screen time and minato+ kushina were better equipped to deal with the nine tails.
