Princeton, Stanford, or Yale for Public Policy/Poli-Sci?

Have to decide by end of weekend and am incredibly conflicted. :confused:

Princeton has the Wilson school, but also grade deflation and the snobbery of eating clubs.

Stanford has amazing weather, but an emphasis on STEM. (Although someone pointed out to me that this could translate to more individual attention and less competing for opportunities).

I like the grittiness of Yale’s campus and there are decent oppprtunities for policy and poli-sci.

Thoughts??
