I was always on the EM trail, but tried to keep an open mind. I kicked ass in medicine, and had my ass kicked in surgery. I was neither here-nor-there with surgery, but my interest was turned away by a sucky, ****ty surgical rotation - my costudents that were really into surgery got more out of it because they were into it from the gitgo. I forevermore stated that if I was told "surgery or nothing" that my response would be, "would you like fries with that?"
I thought I liked IM until I did it (a prelim year before EM), then I came to my senses. When I think of general surgery, there is less parallel than surgical subspecialties (like minor ortho, hand cases, head and neck like ENT, and wound closure that plastics or ENT might do), unless it is trauma - but then there's the paradox: to be a "traumatologist", the best place to be is in a "knife and gun club" environment, but, at the same time, trauma gets old, and then becomes a grind. And if it's minor surgery, it's even MORE minor medicine, which, if you're surgically-minded, would drive you NUTS.
It's not exactly what you asked, but hope it gives a little light.
