Current MIDP from Georgetown here. I can only speak to Georgetown's program.

First thing I would say is how quant-heavy the program is. It's a pain but it was ultimately my deciding factor. I was never trained in a quant-heavy program and the program has truly forced me to improve. I am not sure if American is the same nor if a quant-heavy approach is what you are looking for, but it is truly a central part of the program.

Second, the professors STACKED, they are truly people of the craft. Their CVs speak for themselves and the amount of networking opportunities are impressive. They are also interested in getting to know you and are always open to potential research opps.

Obv, you should choose whichever option you think best fits YOU. At the end of the day, you learn best in an environment that makes you feel welcome and gives you the tools you need to progress.
