Mountain School of Milton Academy or Chewonki Institute - which would you choose and why?

I'm posting here in case parents of college students or college students themselves read this forum.

DS was just accepted to both of these semester schools for juniors for next year. I'm leaning toward Mountain School but DH wants him to go to Chewonki.
If you want to take a look here are the links to each school - http://www.mountainschool.org/podium/default.aspx?t=104841 and http://www.chewonki.org/mcs/default.asp

Does anyone have experience with either school? I would love to hear what you have to say. Thanks.
