It's basically pointless to argue the subtlety of which speciality is more competitive when ENT, Ortho, Urology, etc all have step 1 averages that are so close to each other. When there is a specialty that has a relatively large number of applicants with board scores in the 250s-260s who don't match, I think we can all agree it is competitive. In the January 2013 Urology match, I was fortunate enough to match despite having a below average board score in the mid 220s.
When you are applying to a competitive specialty, board score and grades can only take you so far. Specialties like Anesthesia, IM, EM, Peds, etc don't get a lot of applicants with ridiculously high scores, and programs directors in these specialities will jump on applicants like this. Surgical subspecialties tend to be able to evaluate the entire application of the candidate because there are fewer overall applicants. If you look at the urology match match sheet, there are a good number of people who matched with low board scores. Obviously these people likely did away rotations where they absolutely killed it and impressed the PD and chair. Bottom line: a good board score will help you get your foot in the door if you have no connection to a program, but don't think for a second that a strong score guarantees you a spot. It's all about balance.
I have it on good authority that the average board score of urology applicants was a 243 with about 11 point standard deviation. As for matched applicants, I don't have that information but it is likely right in the same range if not higher. Urology is one of the best kept secrets in medicine. Don't let a lower board score dissuade you from applying, it just means you have to work harder and do really well on your away rotation.
I scored mid 220s on step 1, decent grades, a few non-urology abstracts, but I worked my butt off on an away rotation. At the end of the day, a program wants someone who is teachable and hardworking. Be that person and doors will open.
