jadugar no hunting people down. and your absoultly correct about jiraya saying rasnegan is more powerful (which i believe i said about 2-3 pages back.)

i'll repeat what i said before (at least i think i said it) the power of chidori comes with the ability of speed (with out speed chidori sucks) so when a chidori user can basically dodge the rasnegan, then chidori would obviously win, if sasuke was smart and fought naruto like the way i explained naruto who is bery initiative would've gone for sasuke who could dodge and strike when naruto was completely defenseless.

on the other hand, if they both clash head on like that did in the naruto vs sasuke battle then rasnegan should win because that is a battle of brute chakra power and force.
if you think about it rasnegan is used by those with a lot of chakra (naruto, jiraya) and chidori is used by those with a lot of speed.

it depends on how you use each technique in order to fight.

oh and also, it would appear that when the chidori and rasnegan clashed with kyubi naruto vs lipstick sasuke, sasuke had more chakra reaking out of him or he concentrated the chidori to sharpen it thus puncutring a hole in the rasnegan and going through it to reach naruto. its like the difference between a bolt and a nail. if i were to throw a bolt at you, no matter which angle i hit you with it woudl hurt. yet if i threw a nail i would have to precisely hit you with the point in order for it to hurt you.
