I went to Cal, but UCLA is a great school too. To be honest, just go where you will be happy. If you are from NorCal, I'd probably go with UCLA just to experience living in LA. If you are from SoCal, vice versa. Or if you just really love the cool, hip, urban town like Berkeley and you are from NorCal like me, then go to Cal. If you just love LA's party scene, beaches, hollywood and you are from SoCal, go to UCLA.
In the end, you can't go wrong either way. Just make sure you study hard whereever you are so you can get into D-school.
