The paper does not mention Word Perfect, which some people seem to prefer in some cases. I'm not a user (or affiliated in any way) but I was researching document editors for a project when I found this epic comparison of Word vs WordPerfect in real world use:
25 years ago, I was a secretary. I used WordPerfect, Ami Pro, Word, DisplayWrite and other WP programs. Microsoft Word was just about the worst of the bunch. If it hadn't been for Microsoft's criminal monopolistic practices (OS + office suite), Word would never have become the de facto word processor in the world.
Even 15 years ago I was working as a systems administrator in a company which still insisted on using WordPerfect because of its superiority. A Microsoft fanboy became the IT Director, and WP was phased out for Word.
