The emense cosmic and mulecular powers of Magneto, pit against the God-hood of Raiden. Neither are a joke, and both can be looked at as immortal in one sense or another.
Both of them are my most Favorites of each franshise but...
My Vote Definatley goes to Raiden!!
Raiden has been around longer than and would outlast Magneto. Magneto is mortal. Powerful, and able to mulecularly disagree with the aging process but, nonetheless mortal.
Magneto is Ultra powerful. But I think this battle would come down to who's the bigger combative genius. Wisdom over sheer power. God =Raiden not just Viewed as a God=Magneto
If you think hard enough about this, to "destroy" Raiden...Magneto would have to effectively eliminate the magnetic planes in all of exsisitance only then elliminating Raidens' God-Hood Plain of jurisdiction, but destroying himself and everything in exsistance as well. Picture exsistance without electricity.
Raiden only has to be a solid body when he wants to, and can exsist anywhere electricty is present or possible. He can create it, furthermore "re-create" himself.
Physical abuse isn't an issue for Raiden. cosmic wise is the question here. Magneto is not prepared to deal with Raiden on the level Raiden can take it to. Sacrifice exsistance itself to destroy a being that could still rule the element after his sacrifice? No. Magneto's a genius too, and logiclly, this wouldn't be a feasible equation for Magneto I think.
Magneto is strong enough to give Raiden a problem though. *Understatment*
Think about it.
I am a happy well adjusted emotinally disturbed person, and for some reason all the raiden sprites keep staring at me I mean it tell them to stop, they are scaring me hides 
my friend pred gave me this one, and the avvy that goes with it, but I love the ones flameshang and darkryder gave me too, so expect a cycle of these three folks
