Barnard Precollege vs Columbia Summer Program?

I’ve been accepted to the Barnard Precollege program (summer in the city, 4 weeks) and I just sent in my application for Columbia. Assuming I get into Columbia’s program too, which one is a better learning experience?

For Barnard, I’m doing the 4-week so I get 2 courses (I’m choosing architecture and brownfield investigation), which seems like a pretty good deal to me.
For Columbia, I applied for the 3-week session, for sustainable urbanization(Only 1 course).

I guess sustainable urbanization is what I’m more interested in learning about specifically and the Barnard programs that I’ve selected are somewhat about architecture and sustainable urbanization but not quite, but could help me build a more general and broader understanding about architecture and urbanization.
Also, I’ve heard some pretty bad reviews for Columbia, more so than for Barnard so if I were accepted into Columbia too, which program should I go to?

Trying to make a quick decision before spots run out for the Barnard program since my Columbia application just got sent in. (Counselor sent in the rec letter late :/)
