Minato’s purpouse with the rasengan was always to add chakra nature to it, as stated. And he failed. It took him 3 years to fail adding the chakra nature rather than 3 years to develop the standard rasengan.

Also he straight up stated that he is deliberatly not using SM because it mixes up his fighting style. So there is no debate here as well. I mean you are not using SM when you are fighting the 9 tails itself? C’mon...
