I love LaTeX, I wrote a physics PhD thesis in it and many papers as well. It works phenomenally well up until the point it doesn't work at all. And when you need to go fix something it is a deep and frustrating rabbit hole in my experience.
I think LaTeX starts marginally easy, gets complex and fiddly but then pretty much just stays at the same level of complex and fiddly. Word starts very easy, gets complicated quickly and eventually presents un-fixable problems, no matter what your skill level.
