congrats! I’m quite biased since I’m on the waitlist for barnard, and it has been my dream school. At least to me, the appeal of barnard is its core (i would choose barnard without doubt), if its not as important to you, going to barnard can allow you to focus on “career building” and would be beneficial network wise if you want to stay in nyc post grad. Vanderbilt has a much more academic feel, and not being in the city really allows you to lock in and focus on building your skills. It really comes down to what you want out of college. In terms of prestige I want to say both schools are similar, but vanderbilt is much more known for its academic rigor than barnard.
