They have slightly different philosophies about how they work with their companies. They also have different feels from the perspective of the entrepreneurs. (Not even going to go near the flame bait of trying to sum up the diff --brief for the two companies.)

Also - the different TechStars have a different feel depending on which one you're involved in (e.g. Boston ain't Boulder ;) )

I would talk to a few of the more recent enrollees and a few of the graduates in both and ask them for their perspective.
