So I'm an OMSIII at RVU:
1. the match list for AZCOM is for several years, the list for RVU is for ONE year.
2. The FP vs NP BS, yes RVU is FP, it's not the best thing, many people wish we weren't because it would end the never-ending cycle of BS related to 'but they're FP'... Our dean drives a modest SUV, the nicest car a FT faculty member has is an Audi (pathologist who still practices outside of school) or a corvette (FP who only works at RVU with no outside practice), they have modest salaries, and the owner isn't raking in cash hand over fist because he has to pay off all the bills it cost to build the school. In addition to having to put up the first four and a half years of student loan money for at least 2/3s of the students. Yeah, sounds like a horrible guy...
3. RVU is in Denver, it doesn't get 800K outside in the summer. Your swimming pool will stay a lovely 80º instead of being as warm as a hot tub in Phoenix in the summer. The downside, yes it will snow in Denver in the winter, and could even get what people in CO consider cold. People in MN don't consider -10º cold, but CO people think hell has frozen over. Also, that is rare, most winters are mild and have the coldest temps above 0.
4. RVU has NEVER been slow in replying to emails. Every person I know who has sent Julie or Katy (or Janelle) emails whether they are students or not, have heard back from them within the day, unless it's the weekend or the evening. They call people at 9pm at night to tell them they were accepted. Yes clearly they sound remiss in their duties.
OP, pick the one that feels right to you, no school is perfect, you will have things you do and don't like about any school once you're in, just like anything else... So pick the one that feels the best, and be happy with the decision and the chance to get in!
