To add to this, I find immense value in dealing with text files. In other words, treating them like I treat my code. It plays well with my choice of text editor, version control system, and distribution. Word just doesn't fit all these criteria. Being non-free and proprietary makes it a pretty awful choice for collaboration and distribution. For the same reasons, I even switched to making all my presentations in latex even though I believe Google slides and Powerpoint are feature-wise unarguably superior.
