I have read accounts on CC that identify class availability as an issue at UT. Most likely due to the popularity of CS. I believe (but am not sure) that Turing ensures priority in class selections. Anyway, the availability of classes should be something you look into.
When it comes to internships, the ability to get one during freshman summer is a bonus (wherever you attend school).
Another thing you should consider is how deep each school goes in your preferred area of specialization (if you have one).
