I was looking for the same information last year. I never found any kind of "expert" ranking of immigration programs, but I can share with you what I found from my own research. (I decided on NYU for myself.)
Here are some I think are worth looking into, in no particular order:
UC-Hastings (and Davis, as you mentioned)
University of Arizona
This isn't an authorititative or exhaustive list, but it's a starting point, at least. Good luck to you!
