ND football games are storied for the atmosphere on campus (of course, the ND USC rivalry is pretty big too).
If you are coming from Europe, you might want to research the social rules at ND campus which stem from its Catholic character. All dorms are single sex, students of the opposite sex are not allowed in dorm rooms after certain hours, and having sex is against the student code of conduct (my kid has a bunch of friends at ND, and hears that while the ban on sex is not strictly enforced, it does lead to sneaking around so as not to get caught).
Academically, I would think the rankings are not a significant grounds for choosing – networking and career services more important.
