What's your favorite word processor, and why?

@maguay

I've for years written in mostly Markdown, in plain-text apps like iA Writer and Ulysses, and shared team notes in Notion.

But every once in a while, I'll still need to make a print invoice or make some other more traditional document, and I'll reach for Pages as I don't use a page-centric word processor enough to keep Word around.

So curious: Especially if you've switched most of your writing to digital-first, non-page-focused documents, do you still use a word processor, and if so which one and why? Is Microsoft Word still a core work tool for you?
