Naruto has shitty chakra control. It was said in the beginning of the series. Its the reason he couldn't use bushin jutsu, it was said again when Kakashi thought them how to walk up trees, it was said again during the chuunin exam when Kakashi brought in Ebisu to help Naruto improve his chakra control. Right after that it was said again by Jiraiya but he said in Naruto's case not being at good chakra control wasn't important because he has so much chakra that he doesn't need to be concerned about wasting his chakra.
As for why I doubt Sasuke chidori's is stronger than Kakashi's raikiri and why I doubt Naruto's rasengan is stronger than Minato's is because of this. It was said that an ultimate ninjutsu you yourself create would be more powerful than one you were simply taught or learned how to do. Thus its logical to think that the creator of a technique would be better at the technique that anyone who simply learned or copied the technique. Therefore Kakashi>Sasuke, Minato>Naruto.
Anyway there is another thing, you go on about the amount of chakra Naruto can put out in a burst but what does that matter? You said you need to have exceptional power and exceptional control to use rasengan but the power of the rasengan depends on how much control you have, i.e. how much chakra you can fit into the rasengan. So the better you are at chakra control the more chakra you'll be able to squeeze into the rasengan, so it would make sense that someone with exceptional chakra control would have a more powerful rasengan.
Yeah uh huh, so you're willing to believe that in the three years where Naruto learned absolutely nothing he suddenly became good at chakra control, ignoring the fact that he has no talent for it, and the guy who trained him in chakra control was the same guy who told him not to bother with it. Well you can believe that if you want but it still doesn't help your point. Even if he some how mastered chakra control in the three years he was with Jiraiya it doesn't explain how he was able to use rasengan in the first place.Originally Posted by Uchiha Barles
I missed your stupid comment about Kakashi's rasengan being useless in battle and him lacking power. Now you're just spouting bull.
