I have submitted applications for the online programs at UF Warrington and UMass Amherst. Although I don't want to count my chickens before I hatch, I am thinking about what I do if accepted to both.

UMass is a bit cheaper but I feel like Warrington is more well known in my area (outside of Atlanta.) UMass has a concentration in business analytics, which I am interested in.

Can anybody vouch for either?

My gut feeling is that Warrington might be better for you, in terms of geography, but it would also depend on what the alumni networks for each school look like in the industries /firms where you would be interested in.

I would browse through LinkedIn, looking for the kinds of companies you'd be angling for, and see which school has the better representation. 

Isenberg has better salary outcomes, looking at the FT data.
