I made this same decision this cycle and for me it came down to location.
ACOM is a strong program- with a great match list, great resources, and dedicated rotation sites. I really got the feel there that they were a family. It was my top choice throughout the Fall leading up to the deposit deadline.
During my PCOM-GA interview, I was really impressed by their dedication to developing GA physicians and the GA healthcare force.
I ultimately picked PCOM-GA because its close proximity to what I have already established (home, family, etc.).
Happy to chat more!
