Congrats and welcome to big Dilemma.
Actually, you can choose schools from different perspectives.
1-Those schools are located in big cities but each one has its territory with different corps in every location. You need to consider where you want end up working and living. You may have friends in one city bigger than the others. Some people can’t afford the harsh cold environment in MN and PA so you may think in TX and then MD.
2-The cost of living is really a major consideration. MD seems to be the highest relative to other cities.
3-The way the school not only prepare you for your dream job but most importantly also its attractiveness to employer.
a. Electives: from my view Carlson and cox has most attractive wide electives related to strategy and consulting. The level of electives in Katz and Smith are less. All program has some kind of consulting project but Carlson has its consulting program which starts early which means more consulting and experience.
b. Employment rates: From numbers, Cox is the lowest one with 87% with no info about international students. Also low acceptance for consulting over 3 years, something that makes me skeptical as always average hide unpleasant number. The best is Carlson with 96% with no info about international students but it is more likely that a lot international students secured an offer. High percentage went to consulting. Maybe it is not popular MBB destination, but it seems Deloitte and Accenture..etc recruited there. Katz has also good numbers 91% less than 2014 (96%). However, (92%-94%) international students secured offers in last 2 years. 34% went to consulting. It seems the same tier 2 consulting firms. According to Smith, 88% international students secured jobs, taking into consideration that most consulting is related federal services which is open only for domestics.
From my view, taking all factors above, I would limit my option between Carlson and Katz with leaning more towards Carlson.
I hope it helps. You can add other factors that related to you. You can contact current students to get more info.
Good luck
