MS Word and FrameMaker were never considered competitors in the same market.

Aldus Pagemaker was a closer competitor to Framemaker, but Pagemaker's bread and butter was at the lower end of the market.

see this review for MS Word for Windows 1.0. The competitors listed for their benchmarks include Ami Pro, and the DOS versions of WordPerfect and MS Word.
