When you choose word as the editor you are able to use the full features of that program as opposed to a limited text edit such as notepad or wordpad. This is great for automatic spell checking, paragraph formatting, etc. The main advantage is you get to work in a familiar environment and don't have to learn another program.
You need to be a bit conservative in that some of the features you can add via Word may not be available on the recievers end. Mahalo,
