Outside of large conferences and technical meetups, I find if you compare sheer volume of events/meetups, the valley wins hands down every time. In a given month, I might find 5 events that interests me in SF, maybe more if I really tried. In the valley, you can easily find 5 a week. To be fair, the city has better technical meetups and if you have specific ones you prefer in one location or the other, that's mostly what will matter most.
