Which one would be worse to live in?
Both are extremely poverty ridden. Though i'd say there's less crime/violence in Santo. As much as i hate 6th Street they're not the type of gang to brother civvies. And overall i never see much of shootouts or the like there, it seems relatively quiet.
That said, from a economic and health standpoint the quality of living there is no existent. I think in Pacifica this is better (with the exception of Dogtown). Apparently Kirk lives there.
Curious about your thoughts, chooms
