Throughout my playthrough none of the gangs felt like they were gangs. Mostly they felt like trash mobs, that I exterminate with my gun. During my 160hrs of playtime, I haven't really experienced these gangs, feeling like gangs. So I guess, maybe the Aldecaldos were the best for me. Only because during the Panam side missions, they were really involved with the story and interacted with one another like family. I guess I didn't have that experience with any of the others; as the only interactions with them was from the end of my gun barrel. I wanted to say the Mox, but I haven't came across anytime where the player experience them as a gang. They just sort of hang around lizzy's bar.
