UCI vs UCSB vs UCD for computer science?

Between SB, Irvine, and Davis, which is the best for computer science?

All will give you an excellent education. I would compare the CS curriculum of each school to see if there are any huge differences in the type of courses taught or some specialization that you might have interest. You could also check each schools career center website to see what kind of jobs/internships are being posted. Foremost, which school do you feel you would be the most comfortable in attending? The college experience involves academics/social life and of course affordability so fit is important.
