I agree if you think there is at least a pretty good possibility you will want to be an engineer, Trinity would be a great choice.
I also agree sometimes it is left out of relevant conversations here, probably in part because it is in Texas, where schools with that sort of format are less common than in the Northeast or Upper Midwest. I also think Trinity is one of those institutions that has been good a long time, but it is nonethless also moving up in general reputation.
And one thing I like to point out sometimes is Trinity actually has a really nice endowment, particularly per capita ($656,202 per student according to College Transitions). Schools like Kenyon ($251,340), F&M ($190,395), and Depauw ($407,460) do not have nearly as much.
And of course it would be way too crude to suggest you should always pick the college ranked highest by this measure. But my point is that such resources imply at least two things. First, it is not necessarily a mystery why they can afford to give more aid to students they really want. Second, those resources imply Trinity’s recent reputational gains and such are not a mirage, it reflects a wealthy institution making moves to improve in substantial ways. Indeed, it implies to me there may well be wealthy families and institutions who see the benefit to there being a well-resourced college with that format in Texas.
If you like, you can actually read a little about all this in their endowment report:

You can see them discussing things like how the endowment is helping fund scholarships. There is also a discussion of a large gift from the Semmes Foundation, which is being used for sciences and has led to them naming the D.R. Semmes School of Science. I looked it up because I was curious–the Semmes Foundation is a family foundation, and it was founded by D.R. Semmes, a professor who became a successful oil company president in Texas. Apparently they make most of their grants in the San Antonio area.
Anyway, it is support like that which helps sustain many higher educational institutions in the US. And I would view it as a positive that Trinity is enjoying such financial successes. And if they want you enough as a student to use some of those financial resources on you–win-win, right?
