Have you researched both program's faculty? I'm also trying to choose between MPA programs ATM, and researching the prof's published work has been a useful exercise for me. For example, one of the programs I was accepted into markets itself as comprehensive with both policy and administration streams. However, upon researching the program's faculty more closely, I've realized that there are only two instructors with a policy focus, and both specialize in National Defence (I'm not interested in National Defence, and if I were, I have a better program option for it). That information, combined with the fact that policy coursework is only offered as an elective, allowed me to eliminate the program from my considerations.
If I were you, I'd research every single faculty member in each program, and note how many specialize in international policy (as well as their specializations within that broad policy field). I think you'll get a better sense of what each program has to offer you once you've really dug in and assessed the overarching experience/interest of the program's instructors. Ideally, one program will stand out more because the faculty's research will be more aligned with your interests. Good luck! =)
