The rewards were quite possibly the best that Naruto could have gotten, Naruto gained basically full access and control of the chakra that the Kyuubi could provide, and because of the control over demonic chakra Naruto would never lose control of himself because of corrupted chakra, and the upgrade ticket was also something incredibly useful, similarly to the skill upgrade card he had received at the end of the Chunin exams, which he still hadn't used it would allow him to upgrade a skill, or in this case anything else, including perks, titles, stats, and even weapons.
