The major thing that is similar between the two families is that both families love their kids. But there is a major difference.
Atticus Finch really wants to be around his kids and to do things with them and to let them participate in his life. He doesn't just kind of push them off to the side to do their own thing.
By contrast, Dill's father seems to not really have time to do much with Dill. So Dill is kind of lonely in a way that Scout would never need to be. I can't imagine Scout ever saying that she didn't have a father the way Dill says that he doesn't even though his father is still alive.
