I like Dick and I think he takes the Batman persona and makes it his own, so far what I've seen from him as Batman it doesn't read like Bruce and I love that (like for example how he smiles or cracks a joke under that cowl).
As for Damian he'll end up loving Dick, Batman needs Robin but I think in this case this Robin needs a Batman. But really Dick has a contagious, cheerful, and upbeat personality that makes the most serious tight-butt person smile, he also and makes a heck of a good Big brother (Whatever your opinion is on what happened in the Red Robin comics I still think he's a good big bro).
