LOL WOW ! This debate is pretty heated.
Ok i am going to used the terms the best way i know how.
Provided this thread is in the MOVIE versus forum, we have to assume that the movie iterations of both characters are being used, so no DE sidious or video game raiden.
That being said i say raiden takes this.
lightening seems to be just one of the things palpatine does but its raidens specialty, so im sure his attack is better crafted because he spends more time on it.
when sith do force lightening it seems they have to take a couple seconds to position thier hands then charge it, then send it towards thier enemies, i have seem dooku do this in aotc and and palpatine do it in rotj and it takes all of 3 seconds.
raiden on the other hand seems to have it flowing through him so could probably shoot it out instantly.
so we have 3 scenarios occurring.
A) raiden shocks him to death because he needed more time to gather lightening( which they were both trying to do)
B) siddious force pushes raiden into the wall which knocks him off balance then strikes him down.
C) siddious gets out his lightsaber because he assumes that raiden isnt force sensitive and gets supprised with a lightening death
so raiden takes is 6.6/10
also blax-hydralix if i may lapse into my language for a little while
en repuesto al batalle ente goku y superman, superman lo perdio por que puede ser affectado con el kamehameha que no es energia electrico pero lo es "ki" y por eso goku ganaria.
quando superman es muy fuerte, goku puede destruir un mundo solamente con su energia
