I've started to use Notion for writing drafts because of its very very simple interface (distraction free) and very easy way to drag around paragraphs and ideas. I can easily scrap a paragraph by tucking it into a toggle list but keeping it incase I need parts later.
Extremely intuitive and virtually no learning curve for writing.
Exports Markdown and PDF, but not recommended for publishing (unless your company uses Notion as a wiki or something). Big down side: it still doesn't integrate a spell check.
