Naruto is battlesmart, he does great innovation in battles, and he also inspires people. Now, off battle Naruto is still a brat, but battlesmart is truly smart, once he comes of age he will show his brains; though I think he will end up a pervert just like Sarutobi and Jiraya.
As Naruto is mighty even without the youma chakra, I think it's logical if he ends up battling the Kyubi in the end.
