Which UC school should I apply to?

I have guaranteed admission to UC Davis, Santa Barbara, Irvine, and Merced for being in the top 4% of my graduating cl. I plan on studying psychology and I'm also applying to UC Berkeley, San Diego and Los Angeles, but what I really want to know is which of the schools I have guaranteed admission to is best for what I want to study and all around so I can send my application to them as a safety school?
