For questions like this one I always recommend this book:
https://www.amazon.com/Hidden-Ivies-3rd-Americas-Universities/dp/0062420909
I believe it covers all the NESCACs as well as many like it. Descriptions are unique and in-depth, with lots of academic focus. My favorite college guide on the planet, despite the fact that I hate the title.
