I don't know much about three of those programs but I did interview at UT-SW and really liked their program...but like you, I have multiple programs that I really like.
What stood out to me there (UT-SW) were the residents. Of all the places I interviewed, I felt like I fit in with them the best. The other things I liked were their clinical curriculum - it was one of the few places that I visited where you didn't have to use electives to cover the ACGME RRC core curriculum. I also liked the didactics in place in the fact that there plenty of conferences, including Chairman's conference with just the interns, as well as the format of the AM report I saw which focused more on getting faculty involved instead of just having a bunch of residents sitting around waiting for someone to say "well the patient is in respiratory distress, maybe we should get a chest x-ray". They also had quite a few outside things in the evening like Journal Club and the resident organized Zitelli sessions for broad prep. Lastly, at least for me because I'm single and very unattached at the moment, Dallas is always going to have something to do which in some of my other locations was a bigger question (though obviously in your case, Chicago and Houston certainly won't have that problem).
I don't know if that helped.
I don't think any of your programs are going to remove any opportunities for your future career plans. It's definitely not an easy decision (I certified my ROL 11 days ago and am still pondering changes almost every day). Try looking at where there are real differences that will impact your education - for me that came down to looking at electives and whether the electives were really free for me to pick what I wanted or was I being forced into doing a month of something I wasn't particularly interested in because my elective had to come from the approved list. That's the only advice I really have to give.
Congrats on committing on a ROL, I haven't made it that far yet...maybe I will see you next year, good luck!
