Those are all great choices and it is highly likely that every person you ask, on this forum, or anywhere else, would have a different answer for their top choice. School choice/preference is up to the individual - depending on what a student wants from a school - larger or smaller program, city or not, cost, “feel” of the school, etc. If you can do it, visit! Have your son talk to current students. Congratulations on having a number of great programs to choose from!
