Here's what I use: - LaTeX if the document will have a bunch of equations. - Word for everything else. For me, it's a question of efficiency. I find that I can typeset equations much faster with LaTeX than with Word, and I find that I can typeset general text much faster with Word than with LaTeX. The other issue is with shared documents: if I need to share an editable version of a document with somebody, there's a far better chance that they will be able to use a Word file than a LaTeX file.
