On the whole, regardless of specialty choice, the better/best programs in any specialty will always be competitive. That being said...at one interview I attended (...I honestly can't remember for the life of me where...), the chair mentioned the fact that the application numbers were indeed increased, however the quality of these applicants was not markedly increased.
After having said that though...I met a lot of bright folks along the interview trail. Sure, I applied to academic programs and maybe the quality at Wash U, UofWash, Pittsburgh, and some of the other more noted programs was different than that of a community program, but I thought there were some outstanding applicants out there.
As other posts have mentioned, ENT, Ortho, Radiology, Anesthesia, and the "lifestyle" specialties will often attract some of the "brighter" applicants as they feel that they have worked very hard for their great "reward" and oftentimes rightfully so. This is by no means to take away from their accomplishments.
In the end, it almost doesn't matter what folks say about how competitive a certain field is. I know folks who matched into ortho programs at academic institutions that have sub-mean board scores and were not the "best and brightest." Why did they match? Probably because ortho was exactly what they wanted to do and they were determined to find a spot. Sure they aren't going to top ten programs, but hey, in the end, they are going to be orthopaedic surgeons!
Don't let the comments of others telling you how difficult or competitive a specialty is discourage you. If you network like a crazy man, work like a dog, have a likeable and normal personality, along with some basic competence, you can match to almost any specialty you want. Granted some might be near impossible, but never completely out of the quesiton.
