All of those schools are excellent at STEM and humanities. Neither of your kids could exhaust the depth and breadth of courses available in either area of interest. And the teachers are so good that they can turn STEM kids into humanities lovers and vice versa.
For example, I have a STEM scholar junior who takes independent study courses for math and computer science, but found a love of history last year. I am still shocked when he goes on and on at dinner about the latest history essay that he is enjoying writing. Wait…you actually enjoy writing something other than code???
