Hey,
I have similar situation. One professor I was interviewed with said in business schools usually you are expected to publish your research in top journals which might create a pressure, but is not the case in engineering schools(ofc it is always better to publish in top journals but you got the point). In terms of future income, I feel like engineering school is more flexible, but this highly depends on the school/advisor, whether you want an academic career after graduation and/or location of the school. My best advice is search for previous students on linkedin etc. This might give you a general overview. That is a hard optimization problem I have to say :) Good luck on the decision!
