Hey! I totally get you on this. I also come from a rather prestigious undergrad.
I actually was denied from my first choice and perceived most academically rigorous school in 2020 and ended up enrolling in my third choice. I dropped out in three weeks because the program was not at all intellectually stimulating (the first assignment felt like something for fourth graders, no exaggeration), and it was disorganized/unprofessional. I reapplied this year and in the fall will be attending what was always my first choice to begin with. Both of mine were in state so the cost was about the same.
So basically my advice is to figure out how big of a factor the intellectual stimulation is to you. If it’s the most important, I’d lean more into those options. If finances weigh out, then UT is a great option and it’s a top ten school for sw anyway so your resume will shine regardless.
