As the OP writes more about preferences and priorities, Dickinson sounds to me, at least, like the better fit. Dickinson kids are “all around nice,” active, engaged. I’m guessing, without any data, that there may be more churchgoers at Dickinson than Kenyon. It is also about 500-600 students larger so more room to find like-minded students.
Kenyon student body feels more “urbane” or “sophisticated,” perhaps because the student body leans much wealthier than Dickinson. Walking into the coffee shop at Kenyon feels like walking into some hip coffee place in Brooklyn, with understated wealth reflected in clothing and accessories, and students hyper focused on the latest cutting edge book or article. Of course, that doesn’t describe every student at Kenyon, just the vibe.
