Hi there-- CONGRATS on the acceptances to two fabulous programs, that is amazing! My thoughts on what to look at and consider...
-look carefully at the employment reports from each program-- where are grads going in terms of roles, functions, industries, companies, and even geography
-look at the class profiles for each to see what your classmates will bring to the classroom discussions (at least to get a rough feel as it can vary of course)
-compare the curriculum at each
-visit if you haven't; sit in on classes
-TALK to students/recent alumni at each and get their thoughts on the best aspects of the program, anything they'd change, etc
Good luck on your decisions!
