I had a similar decision to make (ICO vs NECO). Didn't apply to SCCO because way too far.
For me a big part of my decision was the cost of living near Boston. If you live outside Boston to save money, it can take 40 min everyday to get to campus.
Secondarily, some people on SDN say that NECO is on a down trend academically (these were posts from 2015-2018 so it could have changed since). And ICO's board scores appear a bit better.
I also liked ICO's YouTube channel if you haven't checked it out. Since we don't have to visit schools this year, having students chronicle their 4 year journey made a bigger impact on me.
Both are good schools but those are factors that stood out to me the most. I think NECO did a better interview day this year. And Boston is safer than Chicago.
I'm a little biased because I chose ICO, but I think the cost of living was def the biggest part of that decision.
