On what basis did you shortlist them? 

Where do you want to work? 

There are very few schools with a premium reputation in every country. And you might have a reasonable idea of where you are likely to find work. For example, if you are not an American resident you are unlikely to get a job in the US. 

Are there AASCB accredited schools in your country? 

Gies and BU are great programs, and very different from each other.  But start with making your goals more specific and realistic.
