Being in Texas and Austin, UT can’t be beat for price and convenience. I live in Austin too. And if your kid needs something, it’s a short drive for you.
For both CS and business their outcomes will be similar at either school.

GT is a engineering school with 40 majors, and the smartest public school in the country.
UT is a state university with 200 majors, and the second smartest public school in Texas.
The UT academic equivalent to GT is being in UT honors programs - UT Engineering Honors, CS Turing, Business Honors.
GT getting your classes and transferring majors is easy. UT nope, and you can only transfer to less desirable majors.
GT students can live in on campus dorms all 4 years. UT nope, just freshman year.
UT sports…eh. GT occasionally but usually nope.
GT’s campus is actually larger and nicer than UT’s and very green by comparison. UT is claustrophobic and devoid of greenery.
Austin is a walkable town, if you don’t mind the homeless. Atlanta no, don’t do that.
