"What is Best" always depends on what you need. For writing a book, the final answer is probably LaTeX. That's assuming what you need is not highly simple. (However, the advice to work in plain text before you typeset is really solid) However... for something simple, I'll point to https://casual-effects.com/markdeep/ https://casual-effects.com/markdeep/ I've found that Visual Studio Code + https://marketplace.visualstudio.com/items?itemName=Flixs.vs-code-http-server-and-html-preview https://marketplace.visualstudio.com/items?itemName=Flixs.vs... make for a lovely editing experience. Basically, you write plain text, hit ctrl-s and see formatted HTML in a side panel. The homepage explains how to generate PDFs. Here's some notes about fancy typesetting from someone who wrote a book using Markdeep: https://imaginary-institute.com/resources/MarkdeepToInDesign/MD-ID-notes.md.html https://imaginary-institute.com/resources/MarkdeepToInDesign...
