In my experience, the PCH often has LESS traffic because, with the exception of those people fortunate enough to have homes right along the coast (a small minority) most people would be going out of their way to take the PCH anyway.
OP is leaving in the middle of the day, during the summer? Lots of traffic along PCH. Don't you think other people would take PCH if they thought it was less congested? I grew up around the RB area. I would never take PCH down to SD. 405/5 also has some carpool lanes, and unlike here, the carpool lanes are dedicated carpool lanes 24/7.
