The campus. That campus, the quality of facilities, even the food, overall experience, has very few if any peers. The alumni are amazingly supportive. I am an alum and the thoughts of the pep rallies and electricity of the campus on Saturdays still gives me goose bumps.
Bucknell, Lehigh have beautiful campuses too and are strong in engineering but the campuses are not like ND’s. $12 billion in the bank buys a lot.
Boston College is similar but no engineering.
