I suppose this is just the word processing version of "you're not a pro unless you use x". Total rubbish. I used Word to write a 250 page engineering design. Totally fine no issues at all. I would've wasted a lot of time teaching everyone else how to use TeX and messing around on their computers rather than just running a program that people know how to use.
Yeah, why waste time using the best tool for the best job.
TeX has many front-ends that make it as wysiwig as Word, no need for long setups/high learning curves. LaTeX comes to mind. The fact that you didn't know this just tells me that you use Word because you don't know any better, not because it's really "fine no issue at all". You've just learned to live with the issues.
