I think Raiden would since he is an immortal thunder God, doesn't heavily rely on a weapon and knows martial arts. Thor has some weaknesses. I know, they already did some video on YouTube were they made Thor win but I think that's only because Thor is popular and to some people "overrated". An interesting thing to note is that it is revealed in "MK VS DC" that Raiden can defeat superman if you choose the MK side.
