I read through the topics and there are good points raised. My vote is for the newer idea of having death the antagonist.
It's a great idea, because then you get to play with magical bully. Wedgies from miles away, killing guys to have a good seat. Angry looser Death is more dynamic and fun to watch, than some pansy, wuss, weak gay undertone Death. And Stevil is made better because of the new relationship, instead of wooing death over decades, he slapped the shit out of Death the first time he tried something and now does it every time death makes an attempt.
I think it's more fun.
