I agree with everyone else these are very different fit schools, and I would prioritize the one where I thought I would be happiest, including because happy people tend to do better in school.
I also note that they seem to have a similar number of primary majors in Chemistry per year, around 8-10. This is not a bad size for an LAC, but I think it might be worth checking out department and faculty pages to see if one or the other stands out.
