How would any of us POSSIBLY know the answer to your question??!!
Why don't you email some PDs, and if they ever respond, post their responses here?
Chocolate Bear is right on with his statement.
We all understand your "question", as many of us have struggled with the same and/or similar situation(s), but the honest answer is that these boards are a really poor venue for it.
Asking pre-meds for advice about graduate medical education is quite similar to presenting at an ER and getting your exam, medical treatment, and/or advice from the receptionist rather than the physician.
Your question...to be appropriately answered...needs to be presented to practicing physicians and PD's. And...for the love of God...please don't ask just 1 of each!!! You really need to ask the same question to about 20 physicians, AND 20 PD's. Many will have differing opinions...and you really need to be consider them all in your decision.
As I said...most of us have been down this same path of thinking. What I will share with you is the general consensus among nearly every MD, DO, MBBS, and PD I have asked...and I've asked more than 100.
There is nothing wrong with going to any of the Big-4, and any of them will prepare you to be a competent physician...
BUT!!!...for purposes of licensure, and getting a competitive residency...the simple truth of the situation is that you are better off at the
WORST medical school in America (even if it's a brand new for-profit DO school)...than if you go foreign.
Good luck in your decision.
