For me I think brand, network and teaching style are all important but don't know which is more important for me. Stern's and Michigan's brand is much more stronger in Asia than Darden but Darden's network is known to be much better. Also I like the small classroom size of Stern and Darden. Overall I think Stern has the strongest brand in Asia but the number of Stern graduates in healthcare is tiny.
So the reason I would pick the three school would be: Darden for its network and case study method, Stern for its brand and small classroom size, and Ross for its healthcare graduate percentage.
I personally don't know which will help me more or which of these statistics is closer to reality. Will a stronger network really help VC or PE or even just finding collaborators within the industry? Also since Darden is a same tier school will the brand eventually match that of Stern and Ross in the future?
