<p>UCLA imo.
Costs less, as you said, and there is a pretty good social scene here. There are also plenty of opportunities for undergrads here, as long as you pursue them.</p>
<p>Berkeley’s comp sci program is a little more prestigious than UCLA’s, but they’re both pretty damn good.</p>
<p>Visit all 3 campuses and whichever makes you feel the most comfortable, go with that one.</p>
