I agree...it is hard to know before applying which programs are in the "top tiers" and I searched while I was trying to make my interview schedule. It's pretty important as well when you have interview offers on the same day and you have to pick in between. There's also a difference of opinion on "name brand" programs...I'm of the opinion that name brands become that way for a reason, but with that also comes the long tradition and those programs and they tend to be very set in their ways vs a newer less well-known program that is very good, but could be more tailored to the resident.
This is basically my list from what I gathered on the interview trail and where I found the residents to be the happiest. I also agree that it really depends on what you are looking for. If you want to be an academic chair, a place like UMich or MCW might be great because they give you a year of research to build your CV. If you want to do private practice gen PRS, Wake or Grand Rapids might be your best bet. UCSF has some name recognition, but it is a 3+1+3 program which might not be for you. Same with Pitt. Only tip I would give is to look at the entire package. You want to go to a place that will train you very well (which most programs will) but also be in a place where you'll be happy. If you're a city person, don't rank SIU high, even though it's a great program...it's in the middle of NOWHERE!! 6-7 yrs is a LONG time to spend in a place where you're not happy--I dont' care if you're in the "best plastics program" in the world!"
As for aways...I think 1-2 are pretty much required and you want to try to go to a place you're interested in, though it's not necessary. I rotated at one of my "second tiers" but got in to one of the "top tier" programs so just rotating at a place doesn't mean that you're signing up to go there.
Good luck! It's hard...much harder than anything you've done up to this point, but so worth it!
