Gangsta and Black Joke takes place in a setting where there are gangs, violence, and power struggles. There is themes of assassination that involves the main characters as they on powerful individuals/groups. Both series also features the mafia as they get into conflicts with the main characters. There is a noticeable amount of graphic content (and sexual themes in Black Joke). They adapt mature elements that makes their story more realistic.
Both of these mangas involve two partners that are in the criminal business. And while one of them is really good with being social with people and seeing their true nature he also goes around having a lot of one night stands. Then the other one is a brute that can hardly communicate with people and solves everything with his fists.
While the style and the environment is quite different, the story is very similar. So if you liked one, you will definitely like the other.
