USC Marshall vs. McGill business school

<p>I have been accepted into the business schools of both of these excellent schools.
I am from S.F. I can see McGill will give me a chance to experience a new culture, new country (Montreal, Canada) and cultivate new perspectives. It is also probably much better known internationally as an university, especially in medicine. (Often thought of as the Harvard of Canada) But I don't know how well its business school is regarded. I am also worried about job placement back in US.
USC is a good university. But I think it is not as well regarded as McGill internationally. It is also in California and hence won't give me the experience McGill offers.
I would like your opinions and give me some reasons to decie on either school.</p>
