i picked chidori because it has a better penetration force than rasengan and it looks cooler

guess,when Naruro does it with his clones help,it's impressive.;)

its very hard to choose between these two but as I remember they compared the power of Chidori and Rasengan before(the fight between Naruto and Sasuke on the top floor of the hospital)

i think the chidori is more useful to in the fact that you can transfer it into a sword and wield it that way i also just dont like the rasengan its rather annoying really it takes up way to much chakra for a normal person but of course naruto has his cheat sheet

i think the Chidori is better in everything but brute power, so all in all Chidori wins!!!!

well if naruto does his one thousand freakin differnet types of freaking rasengan then narutos mihgt be beter becuase its naruto ut chidori rocks!!!!

I know this from a game, and we all know that games aren't very accurate, but this:

Naruto could break through walls where Sasuke can't break through...

I really think that reason sucks but it helps me believe that Rasengan is stronger than the Chidori.

but in that same game Sasuke could get through walls that Naruto couldnt!!!! (Naruto: The Broken Bond for Xbox 360)

I like both though!!!
