Anything from San Jose to Mountain View is considered the valley. Palo Alto to SF is considered the peninsula. SF is called "the city" in local parlance. To answer OP's question, I wouldn't move there unless I wanted to play the start up lottery. The cost of living is ridiculous and even more so in SF proper. The women are terrible as well and it's pretty boring there. San Jose is about as suburban as you can get. If you want the California experience you'd be much better served moving to LA. it's not quite as expensive (but catching up), the women are hotter, and there's much more to do.
