batman or nightwing?

Which name do you think Dick Grayson should go by?

Bruce is Batman. Dick is Nightwing. for the thousandth time, this is how the universe belongs

I preferred Dick as Batman. I say this because I think Bruce has pretty much done EVERYTHING already as Batman and it was a fresh take reading Morrison and Snyder's Dick Grayson.
 
That being said, I am looking forward to Bruce as Batman with Damian as Robin. That'll be interesting!
