This post is obviously very biased and nowhere near the truth. It can easily be ignored. The MA in Pol Sci at NYU is an excellent place to get academic training. It has excellent substantive courses in all of the areas of political science as well as courses in quantitative analysis, game theory, and formal modeling. Just this semester alone an MA student can choose to enroll in any of 7 courses that are both MA/PhD level classes, just check out http://politics.as.nyu.edu/object/ma.scheduleSpring2015
What this means is that you can get somewhat of a PhD level education at the MA level if you choose to enroll in the right classes. The NYU MA thus does an excellent job at preparing you for PhD study. It is likely the best option from your list.
