I was also deciding between a few programs, among them were
CMU MSCF and UChicago MPCS. I talked to several people (admissions counselors, people working in quant finance and SWE), who said if you want to go into quantitative finance, go
CMU. If you want to go into SWE, go UChicago. If you're set on quant finance,
CMU is probably the way to go.
