Cal Poly Pomona Vs. Cal State Long Beach

Hello, I have been accepted to both CSULB and CPP for civil engineering. I already know that CPP is the better one for engineering, and I already know that CSULB is pretty good at engineering, but not as good as CPP. I want to know which school is the better fit for social/dorm life/ night life and which school is more fun. I also want to know whether or not it is true that if I go to CPP, that I would for sure have better opportunities. I am leaning towards Long Beach because I am a more sociable person and enjoy going out to do things, based on my assumption that that is the more sociable school. What would you guys recommend?
