If my quick review of the numbers is correct, between just those two, Loma Linda would seem to be the better choice. It's a bit cheaper ($30k/year vs, $38k), class sizes are smaller, licensure rates are higher, and match rates to APA-accredited internship (while not great) also look to be a bit higher. However, it does mention on their site that there is a "Christian environment emphasizing integrated learning and compassionate whole person care," which may or may not matter to you.
One very important additional point to consider is internship. Most students will end up moving for internship; if you're limited to only Southern California, you're going to be facing intense competition for a (relatively speaking) small number of accredited internship sites. If you pursue a non-APA-accredited internship, it will limit your job prospects with respect to prisons and, I would imagine, state hospitals.
With your geographic restrictions, other career/education options may ultimately be your best bet. As others have said, accumulating the same debt levels as a medical student when the median earnings of a psychologist are about 1/3 that of a physician can be financially crippling. Psychiatrists, if they buckle down, could probably pay their student loans back in 5 years, and could do so relatively comfortably on a standard 10-year repayment plan. Psychologists would ultimately likely need to rely on "forgiveness" (with the accompanying tax bomb) after 25 years, or hope PSLF is still here when you would eventually be eligible.
