I'm in a similar boat where I have to choose between Baylor and UTSW. No matter who I ask, I am told that both schools are near equal - which they are in nearly every metric (financial, ranking, etc.). I'm from the Dallas area, so I've spent a lot more time at UTSW and it feels a lot more like home for me, but I really, really liked Texas Medical Center, so I'm thinking of visiting Baylor once more before deciding. Although I know the Dallas area a lot better and am more comfortable with it, the wanderlust part of me wonders if a change to a completely new location will be better for me. I'm not sure, tbh; I really did not get to see much of Houston when I interviewed, and I haven't really been to the city much before that.
I will say, though, that some Reddit lurking seems to reveal that general sentiment toward UTSW is that it is very much an up-and-coming school with a lot of forward progress being made, while Baylor might be a little less innovative and have some administrative problems. The personal vibe that I got from UTSW is that the administration seems to be a lot more involved and caring for the students, just based on the way they organized interview days and second look weekends. Baylor's interview day was fine, but it was a lot shorter and I got accepted after their second look weekend, so I wasn't able to see how the school panned out there. Either way, it's definitely a hard decision. Do keep us posted on what you end up deciding!
