A tie between Dick Grayson and Tim Drake. Honestly they proven to use all of Batman's teachings to the fullest extent. It's virtually Batman segundo generation. Not to mention their personalities are pretty awesome as well. I don't like the segundo robin as much as the other two simply because he was way too hard-headed and (IMO) annoying.
I really pag-ibig them all to bits, but if I absolutely had to put them in an order, it would be: Dick Grayson Jason Todd Tim Drake Steph Brown Damian Wayne Which I find kinda funny since that's the order in which they came :3 (BTW I like to pretend that the whole Carrie Kelly thing never happened :/)
The Teen Titans version. I prefer this version of the character because any other versions in my opinion didn't have the same charm as the Teen Titans version of Robin.
