rush is such a great place. the residents are amazing and i have heard nothing but good feedback from it. chicago is, well, its chicago. its right for some people (academics, mostly) and not for others. uic however is definitely up and coming. they have a lot of new research and dollars going into stroke, and they definitely have a big facility. i would say that uic is better than loyola though... i felt like loyola does have biller but, he is new there, he just got there, he just left indiana (which i have heard several stories about, one that he left because his wife passed away, the other because he made enemies with most of the people there and was essentially forced out). loyola has the benefit of brand new buildings and money, but i found it sketch that i met very few of them, and they were uniformly not very friendly to the interview group (standoffish mostly). and, its not downtown chicago, its outside chicago in maywood.
so, if you have favorites in chicago they are likely to stay your favorites whether you go to uic or not. however, if you want to be in chicago and widen your chances of ending up there for some reason, def go to uic. id put it on an academic level, below uchicago and northwestern, but on par in terms of name, with rush, and above loyola. (yes, i know rush has the handle on it clinically, but overall the uic name still holds pretty well.)
thats my opinion on that and it probably isnt the same as everyone elses.
