[MIIS@CMU vs MSCS@Columbia]

Bachelor's in CS/Work experience of over two years at an MNC.

So far, I received admits from these two universities. (Waiting on the others, but Columbia needs a decision in 2 weeks tops.)

A bit abt me
-I want to build a career in ML/NLP. 
-I worked as a quant. So, I did lose some practice in core CS/NLP.
-Interested in a career at an industry after my graduate studies.

Other details
-Both the programs almost cost the same with living expenses. Both of them are ~1.5yr programs.

I want some honest reasons on why, if at all, I have to reject a university of these two.
