If you want to find a good academic job, then go to Kellogg. Wharton used to be a good place for finance phd, but right now it is a common knowledge that nobody consider it as a top program anymore.
If you want to go back to China several years after your us academic job, then your jobs in the us university is far more important than where you get phd. And any Chinese university you may want to join(such as PKU) knows the market very well and can tell which program is better.
