These days it seems that it's mostly "whatever version of Word that came with my Laptop/Times New Roman 12".
We programmers still have our "holy wars" (although I see a decrease of passion here, too, with safe choices like VSC or IntelliJ being more and more the default.) But back in the days, even writers with non-CS backgrounds could wax poetic about XyWrite vs. WordStar vs. Word (DOS/Win/Mac) vs WordPerfect. (Heck, WordPerfect even made lawyers have an opinion of their own)
