Naruto's Rasengan do differ and this thread is for those who think otherwise.
A ninjutsu with preeminent destructive power, caused by wildly spinning chakra inside one's palm and compressing it to a high density — the Rasengan.
NARUTO'S RASENGAN VARIETIES AND DIFFERENCE
1. Big ball Rasengan
Like the original, Naruto uses a shadow clone to help form it and to carry it with him. Compressed to an even higher density than before, the chakra is released all at once as soon as the technique hits the target, releasing an extraordinary destructive power.
1 a.Sage Art: Big ball rasengan
When using its Sage Mode variant however, he is able to use two clones to form the attack in both of his hands and then give the Big Ball Rasengan to the clones to wield by themselves. This technique was capable of blasting Pain's summons high into the air.
1 b.Sage Art-Ultra big ball rasengan
The Sage Art: Ultra-Big Ball Rasengan is a gigantic Rasengan created by Naruto Uzumaki, enhanced with sage chakra. Although its destructive effects have not been seen, it was used to distract the Nine-Tailed Demon Fox. Presumably, it is as strong as Jiraiya's version which was said to be able to hollow out a mountain if it exploded.
Naruto while in Nine-Tails Chakra Mode creates a Big Ball Rasengan in one of his hands, which is then surrounded by three smaller Rasengan, in a similar manner to moons around a planet. When coming into contact with a target, the disordered rotations of the individual Rasengan, created by the central and smaller ones spinning in different directions, interact with each other to form a massive and turbulent cone-shaped vortex. The strength of this technique is so great that it took even a shinobi revived by the Impure World Reincarnation technique a significant amount of time to regenerate, which they normally do instantly.
3. Wind release Rasengan
Naruto mixed his wind element with the Rasengan during his training, maintaining its original stability and increasing its power, far beyond that of his ordinary Rasengan. An example of the power that element manipulation adds to the Rasengan is shown when it was tested against Kakashi's standard Rasengan. The fact that it was only partially completed, but still be able to easily overpower Kakashi's Rasengan and damage his hand demonstrates just how far the Rasengan had been pushed when combined with elemental chakra.
4.Tailed Beast Rasengan
To get around the fact he couldn't use either the Tailed Beast Ball or Shadow Clone Technique while in Nine-Tails Chakra Mode, Killer B advised Naruto to use his chakra arms instead to attempt to create a Rasengan. The results were incomplete, though they looked like a combined version of the Rasengan and Tailed Beast Ball.
5. Twin Rasengan
The Twin Rasengan technique is simply the simultaneous use of two Rasengan by the user, with one in each hand.
6. Spiralling Absorbtion Sphere
Naruto while in Nine-Tails Chakra Mode, forms a Big Ball Rasengan in his hand then throws it above his back. He then uses his chakra arms to grab and smash enemies into the sphere.
7.Spiralling Strife Spheres
Naruto while in Nine-Tails Chakra Mode uses chakra arms to form multiple Rasengan. He can then hit multiple opponents while holding the Rasengan with the chakra arms.
8.Sage Technique: Spiralling Serial Spheres
The Sage Technique: Spiralling Serial Spheres is simply two Rasengan used simultaneously. Senjutsu chakra is added to the technique, which greatly enhances the strength of the attack.
9.Sage Art: Many Ultra-Big Ball Spiralling Serial Spheres
After creating multiple shadow clones with each of them holding a Rasengan, Naruto then enters Sage Mode. The clones then expand their Rasengan into Ultra-Big Ball Rasengan and simultaneously strike the enemy, resulting in an enormous amount of damage, which could even stun Kurama.
The others are bombarding the opponent with hundreds of clones with any of the above techniques
