I've heard this rumor so many times that I actually believed it...that is until I actually went to the place for my interview. I was pleasantly "surprised" by how completely false it was. Now it's just laughable.
Nevertheless, I think the rumor may have emanated from the fact that Hopkins had intense grading systems for a long while (grades then HP/H/P/F). not cool. They recently switched to pass/fail though so they're definitely catching up with the trend and it's all good.
Anyways, to answer the OP's question, if I was in Cali, I would pick UCLA but since I'm since an East Coaster, I'll throw my vote in for Hopkins. I didn't apply to any Cali schools cuz they're too far.
