Well Naruto while training with killer bee also fit better. He gained access to Nine-tails mode but in turn Kurama could take over that much easier and this time it wouldn't be gradual or emotion-based, just that Kurama didn't want to, which is why I felt Sasuke fit more. He had Orochimaru inside him even though he thought he killed him for good inside the genjutsu plus he took some of Orochimaru's stuff for himself and it took Itachi some effort to prevent Orochimaru from having the chance to take over the body.
