All naruto does,is spam rasengans & kage bunshin...
He's just wasting the chakra he gets....
& if you look at it again, from his only 2 speciliaty jutsus, one was created by Minato & 2nd was a forbidden jutsu from the scroll he stole in chapter 1.
All I can say,is that most ninjas would've done better than naruto if they had nine tails chakra inside them.
Because we've seen SO many jutsus from Minato right? Let's see, what has Kishi depicted him doing so far... um... spam FTG, Rasengan and Body Flicker aaand... ah no wait, that's actually it. (yeah he did use the teleportation seal on the big bijuu dama headed for his face, but imo that was a variation of the FTG, he was even holding the dagger after that).
Oh and yes, that one jutsu with which he died.
Don't get me wrong, I love Minato, but imo your comment is irrelevant, thread is not about how many jutsus they can do, it's about whose version of the Rasengan is stronger
On the topic: Minato's base Rasengan does look stronger, but Naruto's improved it over and over again and created a gazillion versions of it that are stronger than Minato's jutsu.
