I did mine at USC, and felt like I got a lot of good teaching there (esp. MSK). They give you a schedule, but tell you to do what you want with it, and to use it as a guideline if you're stuck, so lots of freedom there. The only thing is the letter you get is (from what I've been told) generic, and that everyone (that doesn't completely suck) gets it.
A classmate did his at UC-Davis, and had only positive things to say about that one.
Oh yeah, both me and the above-mentioned classmate (and one other in my class) all matched USC radiology.
