Which is cooler, the 7-colored Rasengan (Naruto movie 1) or the double rasengan (red and blue Naruto movie 2)?

Question

In the Snow Princess movie, naruto was able to do a 7-colored rasengan just like in the movie they watched in the beginning. This is obviously an optical illusion created by the reflected or refracted sun ray through the wall mirrors supporting the Snow country's generator.

In the Stone of Gelel movie, Naruto was able to do a double rasengan, one in each hand--red in his left and blue in his right. His bunshin formed the red rasengan (this is questionable since naruto is obviously not in his kyuubi powered state...although, even if he was in his kyuubi powered state, his rasengan is always blue, as shown in the sasuke and naruto fight in the waterfalls, which is also questionable) while Temujin using a shard of the Gelel crystal formed the blue rasengan in Naruto's right hand.

Articcrow> Odama Rasengan is the result of Naruto's two and a half years of training under Jiraiya. That is way cooler. However, The futon: Wind Release Great Ball Spiraling Sphere is a hell lot cooler. It's the rasengan made not only by form manipulation of chakra but also of nature manipulation. It is achieved by Naruto through a training supervised by Kakashi and Yamato.

But all I'm asking are the Rasengans of the two movies.

Answer 1

I'd say the double rasengan

but wait a while for the Naruto : Shippuden series

and you'll be watching Naruto do "Dodama Rasengan" which is pretty much great sphere (or sth) Rasengan, looks nice in the manga

Answer 2

the double rasengan. it's more powerful and i like how it represents the 2 states of naruto that we know of. like u said, the red vs. blue.
