Office provides far more than just typographic quality. They provide spell check and grammar check which is what most people care about. Many people creating latex, as far as I know, are using text editors which are missing those features or are quite limited.
Actually office suites fails to provide typographic quality. Fails also to provide useful computation and presentation tools for the modern time, spell checking and (limited) grammar checking are not their exclusive as well.
Essentially ALL features of all office suites I know are sub-par to most other classic tools born before them, and they also are limited and limiting.
