From my understanding the University of Illinois has a really great reputation in the field of communication but it definately depends on what you are looking to study. UMASS offers really good programs for specific fields. In my opinion the best way to figure out which school is better for you is to research the faculty that teach the specific field you are interested in. Find out about their reputation in the field and also if research they have done aligns closely with what you want to study. So many people get caught up in which school is better but what it usually comes down to is specific faculty that you want to work with.
