I have had to update my resume lately and a while ago I wrote it using LaTeX
which is a typesetting program. Typesetting programs are different then word
processors as they allow you to focus more on the content rather then laying
everything out on the page. A few cases where LaTeX trounces Microsoft word is
when you are writing anything that uses a predefined layout that must be
adhered to such as a paper written in MLA format or a book. While it excels in
some areas it fails miserably in others, for most use cases anyway. So you are going
to have your work cut out for you if you are trying to make posters, fliers,
banners, and any other type of thing where you really want to focus on layout
while writing.
While I don't write many MLA papers anymore, LaTeX is still the de facto
standard for writing papers in academia and it is great for writing anything
that contains a lot of math equations. If you have ever used Microsoft Word's
equation editor, you can see that it is time consuming and using LaTeX markup
is still not going to be faster then ...
