No, I mean in personality. Take a look between the two current running in rebirth between Red Hood and Nightwing. It's different, the opposite.
You said emotional and angry, while I did see Dick being emotional, I didn't really see Jason as being angry. He's only angry towards Batman and even then he calmed down in the end.
Like it's really different, look at the people they're interacted with, look how it goes, look at what they're thinking, look at what they did.
It's night and day, really really different.
