In the current academic world of mathematics or engineering, most scholarly journals accept articles in the tex files form which are known for their professional type settings and remain flexible throughout all operating systems. It is a known fact that researchers struggle to align and format mathematical equations in WYSIWYG editors such as Microsoft Word. This is also true for figures and tables especially with regard to captioning them and referring them elsewhere in the document. $\LaTeX$ is on editor whose most admirable feature is the clear separation between the content and the formatting of the document.
$\LaTeX$ has an excellent in-built referencing system to label and refer tables and figures anywhere in the document. $\LaTeX$ makes it easy to type equations, to keep the figures and tables at appropriate places and handles the bibliography with ease. $\LaTeX$`s ability to handle the subject indices as well as author indices are also remarkable. The learning curve in $\LaTeX$ is straightforward and unique and as a result, unorganised documents cannot be created in $\LaTeX$. Linked below is one article explaining in further details, the ease in using $\LaTeX$ over WYSIWYG editors - https://tex.stackexchange.com/questions/1756 .
