San Francisco vs NYC

I'm in final rounds w/ two REPE firms (acquisitions). One is in NYC and the other is in SF. Nothing is set in stone yet. I'm hoping to hear from people who have worked in one or both cities - why did you decide to move there, and why did you stay/leave? Both seem like good career moves but wanting some more color aside from the typical rent, weather and stereotype stuff that we all know of. Not really attached to any particular region at the moment. Really appreciate any advice you guys have.
