Wild 7

Both titles where release around the same period (early-mid 1990's) with similar animation and a similar vibe. Both anime deal with police cops fighting against high level of crime across the city. The police cops in both anime kill criminals in the most gruesome ways. Both of these anime are over the top and are both filled with violence, blood and gore. If you like one, you will enjoy the other.  

Crazy cops that punhish crime with lots of violence! 

Both are episodic buddy cop, exploitation, action genre with increased violence and gore level. Wild 7 is mixing criminals made "special police squad" (Oredo 808), production values and comedy (Mad Bull) and the right-leaning extrajudicial ideology (Angel Cop) into a bloody rampage. All three are cut from the same cloth. Wild 7 takes itself more serious than Mad Bull, which uses cartoon violence rather than "real" gore. Wild 7 takes place in JP, Mad Bull in the USA. 

group of convicts made to work for the police in exchange for commutation, with unhinged action, motorbike stunts and all that stylish crap.  

Both are violent cop, exploitation, action genre with increased violence and gore level.

All three are cut from the same cloth. Angel Cop has a supernatural element and has some mystery, whereas Wild 7 is straightforward action in contemporary Japan. The main connecting element is repeated dialog justifying extrajudicial police murder, and some story elements about corrupt politicians.
