We spent a day at each Dartmouth and Brown while on an east coast swing visiting a bunch of schools. I’m sure either would be fine, but when you look at both facilities and course offerings they pale in comparison to state schools that are considered by most on this forum to be fairly pedestrian.
Our son had three WUE safeties, Utah, Colorado State and Oregon State. He preferred all three, by a wide margin to the two Ivy’s he visited. In the end all three got applications, and the Ivy’s didn’t.
Couple that with the fact that Dartmouth requires five years to get an ABET accredited degree and it’s a wonder that anyone applies.
