I second Sac on this...currently a 4th yr at OHSU. It has its flaws like any school, not the least of which is cost, but as far as med students not being well-trained clinically I have in fact heard the opposite at residency interviews I have attended (e.g., people commenting that past OHSU residents they had were particularly well prepared). As for the assertion that med students don't take overnight call, I wish someone had told me that during my peds clerkship, peds sub-I, NICU, surgery, and ob/gyn rotations so I could have gone home and slept. While UW is certainly a good school, I don't know where people are getting the idea that UW students get to write their own ticket for residency- the students I have met from there seem happy enough but I don't think the name carries any special prestige with it for PDs.
Anyway, if you're a washington resident you should probably go to UW unless money is not an issue and you really want to move, in which case Portland is an easy transition from Seattle.
