My current favorites are Power and Ray Donovan. Power is really good if you like the gang/underworld type of shows. It focuses on two best friends and their drug network, the drama, and violence that comes with it. Ray Donovan is basically about a guy that is paid to "fix" problems for people. Think early seasons of Scandal, but more violence and less politics.
I'm also going to binge watch Narcos season 2 sometime soon. Ballers is good but I'm just getting into it.
If you haven't seen all of the seasons go back and watch Sons of Anarchy.
