LaTeX vs. MS Word?

I don't use LaTeX for every single piece of document I have to write. As with most things, LaTeX has its advantages and disadvantages.

Let me write some reasons why I use LaTeX for some documents. These documents have a lot of math symbols inside (yes, I did use it for my statistics journal) and using LaTeX not only makes writing math symbols a lot easier, it makes them prettier. You don't have to open Equation Editor all the time and slowly find your alpha symbol or your greater/equal to sign or your double arrow. You just need to type these commands \alpha, \geq, \doublearrow respectively and typeset your document and here it is! 

Here are the math equations compared (taken from http://amath.colorado.edu/documentation/LaTeX/information/whether.html) 

1a. TeX version	1b. Word version

2a. TeX
2b. Word

As you can see, it's prettier in TeX, and more professional looking too.
Another reason why I use TeX is because I could divide my document into sections and the output pdf will give me each separate section as a bookmark. This makes things easier to find. Plus, the section formatting is pretty simple and easy to do. It can make a title page and a content page, plus you can add footnotes in between your paragraph words, so that you can keep track of your references as you use them.

For these reasons, I use LaTeX.

But of course, I use MS Word too. MS Word is a WYSIWYG, or What You See Is What You Get, editor. This makes it much easier to organise my thoughts when I see the words and pictures out on the screen I am looking at, rather than waiting it to compile then seeing if it works. LaTeX can give you typesetting errors, which occurs when you forget a close brace or backslash command. Sometimes my friends don't know LaTeX so it isn't easy to work with that.

And also, some things are easier to do in MS Word, like drawing graphics or copy-and-pasting things.
