Been to all 4, live in LA, LA wins hands down.
But I love it here, as long as I don't have to live in/go to some parts of it.
One of the coolest things is how flipping multicultural it is, within 20 miles or so, you can hang with Armenians, Latinos, Filipinos, Chinese, Blacks, etc...
The food is pretty good here too, where else can you get Mexican looking food with Philippines flavor?
