I did interview at Both last year
I think Arizona is on the rise from the perspective of research and if that is something you like, then I would consider Arizona. I also personally would hate to be in Houston, so maybe I had this bias from the get go. Both program directors seemed committed and I think they will both support you. I was personally more attracted by U of A, but this is a personal preference. I would believe that academically they may be similar or close, although I remember U of A not being ranked badly at all (don't remember for Baylor, but you can do a quick doximity search, for what their ranking is worth).
Good luck.
