I completely understand your love of GSB after last year, but in a purely non-swayed opinion there are several things to seriously consider. Ross is a strong stable brand right now, its one of those borderline top 10 schools and there is a lot of positive things being said about it lately. Obviously GSB has the better brand but Ross is no slouch in management and consulting...it actually is a highly regarded management program. For me it would be a no brainer for finance, Ross is good there but cant compete with GSB...few schools could. But since you want MC, it requires a little more internal debate.
1) family, AA is going to be cheaper unless your wife scores a visa to work money will be much tighter at GSB. I have also heard glowing things about the significant others group at Ross. My cousin's bf is currently a 1st year and she travels there once a month and loves it. She is planning on moving there, and she is a total NYC girl so obviously AA has to have some social scene. I got the impression that GSB's spouse group is not as active from several discussions but she could definitely find a network there too. (advantage Ross)
2) all the consulting companies recruit at both. For the average student at both, GSB grads have the advantage with the big three. However, as a person with a full merit scholarship you wont be an average student at Ross. Having that on your resume really puts you at the top of the heap, its a clear indication that you are the top x% of the students at Ross. Where as at GSB you will be a typical student competing against other folks, some with merit scholarships, experience at those companies, and in the industry. In the end once you get the interviews you are going to have to nail the cases and that is whats going to seal the deal. Wherever you apply, I think these days your demographic is going to be a big help too.
I said Ross, but you definitely cant go wrong with either. I just think the that the scholarship is a clear indication that you are considered the top of the class. Economic concerns also would be an advantage here, the cost of housing and expenses for two in Chicago will be higher.
I think you should give the pros and cons to your wife let her have her vote, and that can really sway you. She will have your best interests in mind, wont be as biased for a school as we all may be, and also will be able to voice where she would be the happiest. Keeping her involved is key to making it a happy transition, and if she ends up hating where you are she cant blame you
