Naruto/Sasuke didn't defeat Juubito alone. It was essentially the whole Shinobi Alliance + Hokage + Oro's group who were fighting him. Without them, Naruto and Sasuke would've gone down on multiple occasions. Anyway, Naruto has only Kurama + small parts of other Beasts' chakra, while Obito had the whole Ten-Tails, though an incomplete one (with small parts of Gyuki and Kurama), but still Ten-Tails.
