I'm in a similar dilemma, I have been accepted for Masters at Columbia U and Purdue. Both are ranked the same on US news .. and I haven't got any funding from either one of them. Columia seems very lucrative, coz of being in NYC, an Ivy league univ, excellent placement record and active Machine Learning and Computer Vision research(my areas) .. Purdue on the other had, in almost half the cost of Columbia and has higher chances of getting aid as TA/RA in future, but the job scene doesn't look good there. So, money wise purdue is better, but columbia scores everywhere else .. I'm inclined towards columbia, but purdue is still in my mind ..
Can someone list any pros/cons of columbia/purdue, which might help me firm up my mind ?
