I had a pretty good experience with the CS department at UChicago, so I would like to share my experience. I did the Computational and Applied Math major, which required me to take the intro sequence + discrete math + algorithms.

I took the 160s "Honors" Sequence, where we learned Haskell for the first quarter. I would say that learning a functional language was well worth the effort. If any first or second year at UChicago is having doubts about whether they should take the 150s or 160s, I would say that if you have a decently strong math background and some CS experience, then it is worth taking. You will definitely need to work hard though, and I would definitely recommend finding a good partner to work with. Beyond the content, I also think that the people you meet will be the more ambitious and driven types, so it will be good to meet people in the class.

162 (we learned C), 154 (computer systems), Discrete math + algorithms were pretty textbook (but good) in terms of their content.

All in all, the CS classes I took were definitely some of my favorite, and I would highly recommend taking the honors version if you can handle it.
