what i'd say really depends on context. my opinion is that all opinions should be couched in your personal objectives.
there are a variety of grad school opportunities in CA for psychologists. i think the clinical landscape has three top, ultra competetive, research focused Ph.D. programs (Berkeley, UCLA, UCSD/SDSU ) and a number of professional school options. the opinions and foci of prof schools are diverse and varied. there's been lots of recent talk on the board about PGSP/Stanford PsyD, and its probably one of the best professional school options out there.
somethign thats been said many times before is don't limit yourself to one geographical location. many including myself list geographical limitation as a reason i didn't get into grad school/the type of grad school i wanted. don't limit your search to CA. i know its the greatest place in the world but if you want the best chance of getting into the best program possible with the best fit for you, you should probably open up your search to other places and other types of programs.
