I imagine the reasons to choose one or the other given the price point of both is very personal. I think if these schools were really “close” in someone’s decision it could be considering a pro or con — depending on your family’s faith, distance, or some other factor that pulled you. OP: it would be impossible to know who got into both and who chose which and why, but academics is the last reason I can think of.
Belonging is a big part of Holton’s ethos. We just volunteered to be a mentor family to welcome new families in lower school. Holton also has a solid DEIB program with affinity groups for students and parents. My kid is shy and quiet, her question she had about the school is “will they be nice?” There is a strong focus on community, compassion and collective well-being, but if you have a bad experience at an event, it’s hard to shake it off.
Facility wise - there will be gym renovations and a new community hub on campus for socializing and gathering.

I had no issues with the quality of the LS spaces.
