I am a Lehigh Grad, so not necessarily unbiased. We are looking at all 3 for my daughter. It depends on what you value. All three are fine schools. Lehigh is probably best for business (especially accounting or finance) or engineering. Lafayette impresses me for liberal arts. Lafayette campus is nicer than Lehigh and alumni may be tighter. I know Nova less. It’s larger. Close to Philly, which is good for visits (I did my MBA at Penn). Sports are bigger at Nova. I have a neighbor with 2 daughers there who love it. Net, net, net you can’t go wrong with any of them.
