Depends on who you ask... LaTeX is a typesetting system that uses plain text commands to format and structure documents. Has a bit of a learning curve. It also (usually) does exactly what you ask it for.
Pro-tip, at least when I last used Word, hold alt when dragging and dropping images. It somehow fixed the brokenness of the default way of doing it. I think this still works, I just haven't had to type anything up in like 5-10 years, of the stuff I have, I don't think I've ever had to include an image.
