I interviewed at both last year. Ended up ranking UK #2 and MMC lower. Part of that was due to the fact that supporting my family of four on a resident salary would have been challenging in Portland, and they did not allow in-house moonlighting or paid overtime. I'm also not a big fan of that level of winter. I just liked the UK program better too. Randy Schell, their PD, is a legitimate resident advocate and 110% about resident education. Don't think you'd go wrong with either place though.
