I'm a PGY3 resident in PM&R at UCI. My opinion is that all the CA programs are more or less second tier, but solid programs. At UCI, we have 5 per class. In the time that I've been involved with this program, the graduates have mostly ended up at Kaiser, private group practices, or pain management fellowship (1 per year for the past 3 years). I think our program is moderately competitive (there are always plenty of people who want to be in SoCal). My understanding is that we rank no more than 40 per year and we fill pretty early on our list. We take more heavily from students who have rotated through the program, and the quality of the students is quite good.
I think the strengths of the program are a good balance between the inpatient and outpatient experience (basically 50/50), great accessibility to attendings, good facilities (we have a brand new rehab inpatient unit at UCI that just opened a few months ago), teaching locations are all fairly close, friendly residents, location, and at home call. The weaknesses are lack of residents doing research (there are opportunities), residents need to be motivated to keep up on their reading, the VA has its share of typical frustrations.... there are probably other things, but I'm pretty biased and I love this program! 🙂
Let me know if you have any questions. I don't think you can go wrong with any of the CA programs.
