Hyper Police

Both series are about freelancers who try to make a living fighting crime, while barely managing to avoid the law themselves. Also the characters have superpowers: Natsuki and Ginji have electrical attacks, Ban has the "evil eye", and Sakura flies and stuff. Hyper Police is a more fantasy setting with more comedy and ecchi, while Getbackers plays up the drama. Still, I think it's a good recommendation.
