as i said, personally i recommend wharton simply becoz of its better reputation in china generally. I agree that u should choose the school that u will take even there is no $. i guess u've made ur mind when u choose wharton at the beginning.
To me the excellence of my peers at school matters a lot, they are where you learn most from and stay life-long contact with. Booth offers you money which means you are more qualified than most of them, thats why I would turn it down and go with Wharton, let alone its other well-known strength over Booth
