Please don't let this sway you too strongly, because I am not an expert. But as I an international applicant, I can provide a (subjective) comment on the reputation of these outside of the US...
From where I stand, the only program you listed that would be viewed with "equal prestige" (although the idea of prestige is subjective and somewhat petty) as MSFS is SAIS. If you are not bothered by the heavier focus on economics at SAIS, then I personally don't think you should view the degree as any less valuable than MSFS. However, Fletcher isn't too far behind either.
But the relative weight of these programs might seem more balanced in the US.
However, if finances are a big factor in your decision making, I don't think the minor difference in prestige is worth paying significantly more for MSFS vs Fletcher (for example).
