Full disclosure, I am waitlisted at UChicago and it is my dream school so I am inevitably biased. However, with my current acceptances for tomorrow's deadline, I had to make a similar, very difficult decision between two great schools. One ended up being significantly cheaper after aid, but the other was a better fit for me overall after hard thinking. Ultimately, I decided to go with the school where I saw myself happiest. I know that the loans will be paid off eventually, and I am more likely to regret going against my gut feeling than picking the more expensive option. Idk if that helps at all, but best of luck with your decision!
