Probably you've heard that only real men write LaTeX using plain text editors. I'm not a real man enough, so IDE like TeXnicCenter or Texmaker is needed :p
These days, personally I use Pandoc or Halibut (https://www.chiark.greenend.org.uk/~sgtatham/halibut) for anything not complicated. Or if working on team, then 'unfortunately' MS Word. Well, not every of us are nerds :)
No, we have CS interns from the local college who invariably ask about it. We only have them for a few months, so I've probably answered that question several dozen times in the past few years. I know they use LaTeX for their papers as required by their CS department, so I know why we get the question. I'm just tired of answering it.
> Word is a pain if you need something other than very standard formatting.
I don't disagree with that, but our standardized formatting is to use the default styles. Use Title for the doc title, use Heading 1 for each major step or process if the doc has more than one (most don't) and Heading 2 for each individual step. This means the Navigation Pane serves as your document navigation. Most of our docs are less than 20 pages or so (and most of that is screenshots).
I would advise anyone who values their time against using LaTeX for any document that doesn’t primarily consist of mathematical formulas.
Another way of gaining this advantage is to use something you're already paying for like an internal wiki.
It’s a typesetting tool designed for producing paper documents. You should use it for your company’s magazine, menu, posters, and published books, not for your auto-generated technical documentation, your blog posts, or your internal emails.
The previous commenter wrote about what to do if you “don't want to spend a few $10k on professional typesetting software.” That’s much steeper than most people will spend on professional typesetting software.
It’s almost impossible to do professional quality typesetting in MS Word. Last time I really tried was about 10 years ago. I spent like 4 hours trying and failing to fix basic typographic mistakes in another person’s 20-page document, and then gave up and did the whole thing over in InDesign in 20 minutes, with great results.
In LaTeX, you can theoretically do anything you want but unless there’s already a template for it (or you have numerous or long documents targeting the same output style, for which you want to make a template and then mostly rely on automatic layout), it’s going to take a huge amount of time. It’s a good tool if you want output that is “good enough” for many practical purposes without direct human input, but it is especially difficult to do anything special-cased for a particular spread (moving images, text boxes, diagrams, ... exactly where you want them).
LaTeX is great for things like auto-generated documentation, long structured outlines, legal documents, or math papers full of complicated formulas. LaTeX is abysmally ineffective for posters, magazines, or the like. I find that for the vast majority of content in between those extremes (e.g. college humanities homework, non-technical journals, resumés, menus, coffee-table books, novels, poetry, personal letters, ...), InDesign ends up giving nicer output with less headaches.
From what I can tell, Adobe follows the more technical approach, though I’ve only looked over my wife’s shoulder. The fact that I’m just producing PDFs with LaTeX is also different. If I’m writing a web essay, I don’t mind using straight HTML/CSS, even markdown doesn’t really convey many benefits for me.
InDesign is used when you need precise control of the output. For instance controlling exactly how figures are placed, you might more advanced control of how text flows between boxes, etc. It also has tools for very precise control of how the type is set, how big space should there be between letters and words, how should the right edge of columns look, should there be different number of columns on different pages, etc.
Some of those things can be somewhat managed in Word, but you'll have to fight a lot of the automatic stuff, really not worth it if you are a full time design professional, much cheaper then to buy an expensive InDesign license.
Latex is pretty good at having sane defaults. This was a bigger issue back in the days when the defaults of Word were frankly terrible. Today it's to a large extent about style choice. If you publish in an area where Latex dominates, the Latex styling will make your document appear as more serious. Latex also generally uses a more advanced type setting engine, for example it might join "fi" with ligatures etc. This can also improve the look of the document.
Some people like the fact that you can manage Latex code as raw text. For instance using a VCS to manage version history. Word has some built in version management functionality, but it's quite clunky compared to Git.
Personally I gave up on using Latex after my first master thesis and tend to use Word. I get too caught up in the formatting when I use Latex. Maybe it's too much power to handle for me?
Curiosly, I found one while browsing at https://www.overleaf.com. LaTeX again :D
There's also other advantage to using LaTeX, and that is the flexibility that comes with macros. Need to change some notation mid-way through your writing? It's trivial if you've used macros. Need to simplify some commonly used pattern? Define a new macro!
Each tool has their place. Except Word, Word just sucks! (j/k, Word is brilliant when doing collaborative edits with non tech-savvy people, the track changes functionality is great, and not easy to replicate in other environments)
Is a lot of documentation written in LaTeX? I would never use it for that. Paper that is going to be submitted to a conference? Sure! Blogpost? No, documentation that is read only online...also probably not. But I don't think I would use Word for that either, Word is a pain if you need something other than very standard formatting.
