Fellow Norcal-ian here (hi!). Went to UCSD for undergrad, currently finishing up a PhD at Columbia. Little siblings currently in undergrad at UCI and Cal.
If cost isn't an issue, come out here. The education is comparable between the Ivies and UCLA/Cal, but the opportunities for networking and personal growth are way better out east. Staying in CA was a fun, albeit somewhat sheltered, experience. I met a lot of cool people with similar backgrounds in SD and we had a lot to connect over. But out here, I've met people from all over the place (lots of international folks here), Columbia and the Ivies are world-renowned, and as much as I hate to admit it, the name appeal goes a really long way with employers and other schools. And it's not that cold! The city is always buzzing with activity, the subway stations are warm and dry in the winter, the holidays are beautiful, we have actual SEASONS, and you can always commiserate with your fellow Californian expats!
