If you must match in Chicago, then I'd follow the advice of GoSpursGo as the two programs you list will undoubtedly get you to where you want after 3 years of training. As an aside, I'm currently a first-year fellow and would advise going to any programs just because they are ranked highly. Sure you will get good training at #1-20, but you could possibly get equally good training at #20-50 and beyond. I say this because I went to a program that from a ranking standpoint is not spectacular, but I received good training and had a fantastic work-life balance (imagine that for a resident!). I knew I wanted to do a fellowship, so I figured I'd work my butt off during fellowship with patient load and go to a residency that was not as clinically heavy, but had a strong research infrastructure to help me get the fellowship I wanted. In the end, I had plenty of time for hobbies and research and easily passed peds boards without too much additional studying - and this was true for others in my class as well. I'm only mentioning this because it's easy to get lost in the rat race during medical school, but for me, I can't imagine working 70-80 hours/week for 6 years in a row. I was very happy with my 50-55ish/week during residency. Lurie will work you hard and I suspect UChicago will do the same - really up to what you want to get out of residency.
