Drexel, Lehigh, or Lafayette?

I am a freshman in college. At the end of this semester I will be transferring to a new college. My choices are Drexel University, Lehigh University, and Lafayette College, all in PA. I want to have many choices of activities to do while I'm at school but I also like a pretty campus. So I can't really pick from that. I will be in mechanical engineering and doing the co-op program no matter where I go. Any information or personal experiences from these schools to help me decide would be great! Thanks!
