I wrote in another thread about Stanford vs UC Davis but thought I would include in this sticky thread for future reference (Just putting the relevant stuff):
A few years ago they were pretty equal, but Stanford is the better residency now (and will be the better residency for awhile). I have friends in both departments, so I have some idea what is going on (I interviewed at both places a few years ago and I have friends who matched there) although my residency isn't on the west coast.
Stanford is a step behind UCLA, Casey, USCF but I think with all the changes taking place at Stanford, the expansion of the residency, the addition of new faculty, etc its going to be on that top tier soon. Loma Linda and UCD seem like the two weakest on the west coast from what I have heard from my friends in California--basically they operate like community programs like CPMC, although CPMC provides as better experience than both.
.....
There was another comment on SDN about how UCD doesn't care about their residents (in the thread about each program), and that is what I have heard. It does not seem like a malignant place where attendings physically attack you, but I head its not very supportive either--the residents are just there to see patients and be in attending clinics. It is a pretty small program (probably a little smaller than Stanford now, but Stanford is also expanding a lot). I heard the surgical experience isn't that good (average-to-good numbers for some things, but very low in several others). It seems more similar to some community programs I saw on the interview trail. I heard the teaching is not very good--seems like the residents I know there are just waiting out the clock until they leave. The overall impression from talking to current residents I know there is that its a pretty lifeless department.
