How to decide:
1. What are your areas of interest? Those three programs have somewhat different faculty profiles and course offerings. Which group best fits your interests? e.g., if you're interested in philosophy of science or Buddhism, you're shouldn't go to Milwaukee. If you're interested in Kant and German Idealism, UWM might be a good fit. All three have faculty in value theory, but of course, with somewhat distinct approaches and strengths.
2. Placement: you should ask SFU about their recent placement into PhD programs. My sense is that it has been good, and I'm not sure why they haven't updated their placement info. In this regard, I would be at least cautious about UWM - they appear down a few faculty at the moment. Maybe this means they're hiring, but you'll have fewer course options at a smaller department.
3. Funding! This might be the most important. Don't forget to take into account cost of living differences. Vancouver is probably the most expensive place to live of these three locations). Are they also offering the most money?
4. Departmental culture: talk to the current graduate students and get a sense of how much attention they feel like they get, what the atmosphere is like etc.
Good luck!
