I wouldn't say SF's climate is that good - SoCal weather is far superior. And many of the San Franciscans I came across during my time there were pretentious and snobby. The rest of the Bay Area wasn't any better, and I'm much happier since moving to NYC.
I won’t argue about the climate, obviously SoCal is sunnier but I never was a fan of the heat waves and smog of LA. My own personal definition for a good climate is a temperature that gives the ability to do things outside year-round but I do love visiting that part of California!
