I'm in the same boat. I am leaning towards GW though -- only because it has more name recognition outside of DC and the location is more convenient. Although AU's campus is more "college-y", I think I may prefer GW's urban campus. I've heard the programs are pretty equal, quality-wise. Neither of them gave me any merit aid :| -- so don't have to factor that into my decision. Got waitlisted at Georgetown, I think I may go ahead and get on it and see what happens. I think I would pick Georgetown over both of them if I had been accepted.
