A few features I've put into these modules that I don't recall seeing in others are:
1) These modules allow you to retrieve ALL estimation results. For example, you can retrieve the covariance portion of the variance-covariance matrix, an option I don't think is available in other modules.
2) Saving estimation results is separated from outputting to LaTeX. This allows you to manipulate your results using Stata commands before outputting them. Most of the other commands make this all one step, which I find inflexible and cumbersome when writing code.
3) -texsave- retains full compatibility with Scientific Word when outputting tables (so table buttons etc. are usable in that program).
4) -texsave- allows captions, lets you set the size of the table, and lets you set column alignments and column lines/borders.
Again, I'm sure I have many features missing since I'm not a LaTeX expert. I've pretty much just added features as I've needed them when writing papers. (Spending hours updating tables by hand every time your numbers change is an enormous waste of time, plus it's subject to human error. These commands have eliminated those problems for me.) As for formatting, I try to produce tables that look like those published in journals like AER, ReStat, etc.
