These are two very different schools, but I’d be interested in hearing the positives and negatives of chemical engineering at both schools.
Check out who the professors are, sponsoring companies (Dupont for instance;) and research opportunities. Do you want a large campus, or small? Yes, these schools are quite different. It might be helpful to check out daily newsletters or call the departments and visit to get a sense for which is best for you. http://www.udel.edu/udaily/newonudaily/https://manhattan.edu/news/manhattan-magazine.php
