I've been DREADING just the thought of deciding whether to specialize or not. To be absolutely honest, it is, in my opinion so not worth all the time and restless nights of studying and just emotional stress. However, I also understand how it's beneficial in optimizing a person's options. With residency/specialization being so difficult to get into, it's hard and almost depressing sometimes knowing that you gave it your all and still don't get into a program you want..
Since we're on the topic, I know for sure endo, ortho and OMFS are extrememly competitive but I'm assuming the other programs are not? For example, I heard that for pedo, your personality matters more than academics. Not saying that you don't need to work hard, but you dont need to be in the 95%-ile in the board scores or top 5 in your class ranking. 🙁
