Congrats on getting into both programs. I've never been to other schools, but I believe Fuqua has a decent entrepreneurship program that is growing. If you haven't, you should check out Fuqua's Program for Entrepreneurs (
https://www.dukep4e.org/). Howie (Director) does a good job in bringing in speakers to talk about all aspect of entrepreneurship, from IP protection to raising capital. We also have start-up challenge and business plan competitions, which have a fair amount of VC in attendence. There're also a few incubator/accelerators in Durham, even a non-profit incubator. I think the only downside of entrepreneurship in Durham is that there aren't as much computer science talent for doing a startup in a web technology sector. The upside is that for biomedical type of startups, the RTP area is very strong.
When you are making your decision, think about what you want to do immediately out of school. If you want to go into industry and then transition into entrepreneurship after you've gain some experience and credibility, I would recommend to go to a school with a better connection/reputation in the target industry. If you want to start a company immediately out of school, you should go to a school/location with strong startup connections in your area of interest. Startups are a connection heavy business and VC tend to invest within its immediate area.
