Here is my ranking of TX law schools:
Tier 1 = UT
Tier 2 = UH, SMU
Tier 3 = Baylor
Tier 4 = TTU, South Texas
Tier 5 = the rest
Between UH and SMU, whichever is cheaper is a better option unless you have strong ties to either city. (27% of lawyers in Dallas County attended SMU compared to 3% from UH; but 25% of lawyers in Harris County attended UH compared to 2% from SMU). Both schools have similar biglaw placement.
I rank UH higher than Baylor because it places about twice as many lawyers in biglaw and costs less (although my guess is that many people with an acceptance to UH will get some scholarship money from Baylor).
TTU and South Texas is a tossup depending on where you want to work. TTU has a slightly higher attrition rate but slightly higher biglaw placement (not enough to really make a difference). The major difference is location. South Texas is in a major metro area, and one out of every four lawyers in Harris County is a South Texas graduate.
I'd say that any school in one tier below can be a better option than a school one tier above if you have a full ride (e.g., TTU full ride > Baylor full price; Baylor full ride > UH full price). This suggestion might not apply to UT, although some people at UH and SMU with full rides were admitted to UT.

I don't have many anecdotes, except that I got a bad "vibe" from Baylor when I visited a few years ago. But I know a lot of Baylor grads, and they are all awesome people. I also have a feeling that TTU's applicant pool will suffer a bit if/when the University of North Texas opens a law school (supposedly happening soon), assuming that North Texas will have similar tuition. Except for TTU, it will be the only public law school north of Austin (and Dallas > Lubbock).
