Maybe his father used a better and more advanced seal than any other Jinchuuriki had. It did allow Fox chakra to mix with his own for his entire life. Or, maybe it has something to do with the way Minato sealed away half the Fox's chakra in himself and only sealed part of it into Naruto. Maybe it has to do with the nature of the Fox itself. All the Jinchuuriki we have seen have shown different characteristics. Compare the powers Gaara had with the powers that Bee has, for instance.
Naruto's heritage might have something to do with it, but there are a lot of other factors to consider as well.
