Congratulations on having multiple options of B-schools! Since your future career goal is MC, TUCK is no doubt the best one among these three, then Darden is better than Duke. On the other hand, those IB firms like to recruit at Tuck for their Asia offices, while this chance in Darden and Duke is very slim. Darden's case method is great for future MCs, however, the equally tough program in Tuck is also great for consulting career. You can check their employement date and then get the feeling how stronger of recruiting at Tuck than the other two.
As for life part, the weather in Tuck is of course the worst one, with at a least 5-month long snow season; not sure about if there is any nice chinese food place in Dartmouth, but I am sure you will have more opportunities to eat lobster. The weather condition in Darden and Duke is about the same, no good chinese food in Darden, but there is a nice Shichuan food place in Duke area.
Disclaimer: I am a Darden admit, and I love Darden; but I have to be honest with you, Tuck is better than Darden (you can forget about Duke if you want to do MC) |
