The big difference is in the amount of academic work, but this varies greatly among institutions. They should all have course information on their web sites. When I got my degree from University of Toronto in Performance, I took electives (French conversation and literature and psychology), and courses such as composition, music history, ethnomusicology, theory and conducting. At the time, I could not have imagined how useful it all turned out to be. Some classical music programs also offer things such as jazz and career-management. Wherever you go, look for a school which will offer playing opportunities in ensembles.
