I'm a 3rd year at Tulane. I cannot emphasize how much I hear my fellow students say how happy they are they made this choice and how much more fun they have compared to friends at other med schools. First off, we are generally nice, not-so-competetive(for med students), and even the faculty encourages us to be well-rounded people. Faculty members actually participate in our music and art shows and some even in our intramural sports teams. Our Dean has a History of Medicine Wine and Cheese party at his own home every year!
And, location does mean something. In January when you are already bummed out about studying so hard, would you rather trudge through snow from your car every day, or wear a light jacket and sunglasses? Plus, there is just so much to do in New Orleans all the time. For example, last weekend, when we finished up one of our two-month clinical rotations and had a weekend off: Friday afternoon I played golf. Friday night, class party at a bar on Bourbon street. Saturday all day spent at Jazzfest, where you can see over 60 bands on 10 stages(EACH DAY of the 2-weekend/7 day festival), eat from a variety of food booths, including about 20 ways to eat crawfish, all for just $18 admission plus food and drink costs. Sunday went to the campus gym and lifted weights with friends, followed by a bike ride on the Lakefront of Lake Ponchartrain. I challenge any other non-New Orlenas med student to describe such a fun-filled weekend without leaving their med school's city. And this is NOT an unusual weekend for this city. It is truly important to feel you can relax when you have the time to during med school and if you go to a place that has so much social life opportunities built in, it's much easier. Plus your out-of-town friends are very likely to visit. Med school is hard work, enjoying your life when you can is majorly important to your mental well-being.
ALL MEDICAL SCHOOLS IN THE US ARE LOOKED UPON FAVORABLY BY RESIDENCY PROGRAMS. Look at any research article ever written on "what residency application committies look for in in applicant", and all will put med school attended low on the list of factors they use to decide between students. It's a fact. How you do at your school, on the boards, and espeially on clinical rotations and recommendation letters is far more important than some minute difference between the three very good schools you are choosing between.
So go where you think you'll be happiest. Did the students seem like people you would like to work alongside? Did the student seem generally happy? Were the faculty approachable and are they willing to listen to students suggestions for improving curriculum? Did the students have any sort of outside life or partake in whatever activities you enjoy doing in your free time? Ask yourself these questions and you will make the right choice for yourself.
