Okay don't try to make an argument based on genjutsu thats just ridiculous. The level of genjutsu Kabuto used during the chuunin exam and the level of Genjutsu Itachi uses are two very very different things. Oh and the reason Naruto got caught by the mass sleep genjutsu was because no one taught him how to break genjutsus yet. Kakashi himself said he only taught it to Sakura. Whether Naruto is good at chakra control or not he now knows how to get out of them and I think he would be able to break out of most low to mid level genjutsu simply because he has so much damn chakra he can simply overpower the technique. Just like what he did or tried to do with Itachi, but that alone wouldn't be enough to escape from high level genjutsus like Itachi uses.

Anyway as far as chakra control goes Naruto sucks at it, that is why he still needs to use shadow clones to form the rasengan.
