@pat07ek Good luck. I agree this thread has diverted from your needs. The clear answer is there isn’t a clear answer. You are blessed with four wonderful choices. I wish you all the best!
Now back to my popcorn while I watch a few adults with too much time on their hands fight online. When it slows down I will turn this into an iPhone vs. android fight. 
“But I almost think it is irresponsible to push Austin which would mean 50k more additional debt for this family when OP is going to go to grad school and despite your low opinion, UMass is regarded by many as a top school with a quality CS program. Amherst is one of the top college towns in America. And the five college consortium that UMass has offers an elite opportunity to study at some of the very best LACs in the country.”
I’m not pushing any college just answering the question the OP asked. Saying all four colleges are great may be accurate but it’s not an useful answer and it doesn’t help the OP. Austin has good weather, diverse campus and strong programs across the board in addition to an excellent CS program. I can’t answer the debt question as that’s for the OP and family to decide. Boston is diverse, but we’re not comparing the cities, we’re comparing the campuses.
