What are the advantages or disadvantages of using LaTeX for writing scientific publications

What are objective advantages or disadvantages of using the markup language LaTeX instead of a WYSIWYG word processor like MS Word or LibreOffice Writer?

Please use objective arguments to prevent a flame war...

Answer

LaTeX is better at:

• Dealing with mathematical notation. Layout and entry are generally easier using LaTeX than some other sort of equation editor.


• Consistent handling of intra-document references and bibliography. As of a couple of years ago the major WYSIWYG editors still had problems with re-numbering cross-references and bibliography items. This is never a problem with BibTeX or LaTeX.


• Separation of content and style. In principle this means that you can write your document without caring how it is formatted, and at the end of the day wrap it in the style-file provided by the journal publisher before submission to conform to the house style. In practice some of the journal publishers demand special formatting commands that partially moots this process. Furthermore recent versions of Word and LibreOffice Writer, when properly used, should be able to keep track of various levels of section heading separate from the body text, and apply uniform styling to each level. The gap is somewhat closing.



• Tables and illustrations. With PSTricks or TikZ, one can produce high quality illustrations within the document (though the learning curve is a bit steep there). And I've found LaTeX to be better at preparing complex tables.

WYSIWYG (especially Word and Writer) is better at:

• Collaborative editing. Without using an online site for collaborative LaTeX editing (such as ShareLaTeX), working collaboratively on a LaTeX file ideally requires some sort of separate revision control software. Word and Writer have very good comments/annotations and edit-tracking features. When a large number of authors are commenting on the writing of one file, this can be very useful.


• Spell check. Admittedly most text editors one uses to edit TeX files also do spell check. But this is generally conveniently built into WYSIWYG editors.


• Compatibility. Unless you work in mathematics, computer science, or physics (and sometimes even if you work in those fields), it is more likely that your collaborators will know what to do with a Word or Writer file than a LaTeX file.


• Minimum barrier to entry. If you just care about getting the ideas down on paper, you can use a WYSIWYG editor just like a typewriter. Sure, it may be tedious to fix the formatting later on, compared to LaTeX where one need to first figure out how to setup a bare-minimum file before using, it may be an attractive point.

A wash:

• Most journals provide templates for both Word and LaTeX, so there's no real winner there.

Suggestion: if you want to convince someone to start using LaTeX, start them out first in one of the WYSIWYG environments designed for LaTeX first (for example LyX). This will help somewhat to ameliorate the scary entry barrier.
