There is not much argument in the way the UC's are rated in general. They are 1) Berkeley 2)UCLA 3) San Diego 4 and 5) Irvine and Santa Barbara depending on the major 6) Davis 7) Santa Cruz 8) Riverside and 9) Merced. However, the ratings would change if you rated by a specific major..

I searched around but found little, so this is all I found. Santa Barbara is very popular and is known as one of the best UC schools. Hope this helped:)

I'm pretty sure they are UCB, UCLA, UCSD, UCI and UCSB/Davis, probably in that order.
