In my 22 years of work experience in Dallas area in telecom, engineering and software development, I’ve worked with some very talented people, I have always been impressed with colleagues who graduated from UT Austin (every single one). SMU on the other hand, well not so much. UT Austin has a reputation for a reason.
If my son (currently a junior in high school) is not accepted to UT Austin and does not go out of state then UTD would be his next choice. SMU would not even be a consideration.
Congratulations on being admitted to UT Austin and good luck to you in your decision.
