Stevens Institute of Technology or University of Delaware or Drexel for Computer Science

My son is a HS senior. He was accepted into Computer Science for University of Delaware(honors program) , Drexel(not accepted to Honors Program) , and Stevens Institute of Technology. Major benefit of Drexel is The Co-op Program. Due to scholarships the price is same for UD and Drexel. SI’s offer is $4k less per year. Stevens gets very high marks for their CS program. I am looking for comments from those knowledgeable about these three schools and the respective CS Programs. . All 3 campus offer a very different college experience. Thanks in advance for your responses.
