Our students have some overlap, and they would have had more if my son hadn’t eliminated ASU because of the heat and UIUC because I’m an alum and it is in the middle of nowhere.
My older son applied to Pitt for engineering as a likely admit (are they safeties anymore?), and we were pleasantly surprised during the campus visit. For a mid-sized (26,000 students) public the campus feels small and manageable, and Oakland is a nice neighborhood. Pitt also has a cross-registration program with Carnegie Mellon, which is right next door, so your student might get to take some classes at The Nerd Farm. If your student decides on Pitt, look into their honors program where students get priority for registration, research opportunities, and - I think - some monetary awards.
