I think Vellum's whole value proposition is typesetting ebooks and other "rich" formats. I've never tried to sell my writing, so Pandoc with a bit of custom CSS has worked great for me, but if I ever feel the need to build a fancy ebook I'll be looking at Vellum first. When I first got serious about writing fiction I used Vim (with Markdown), then switched to Scrivener, but I can not deal with the rich text crap anymore so I went to Obsidian for the best of both worlds, sort of. If Scrivener had a plaintext mode I'd probably still be using it. WYSIWYG editing is a curse on mankind. Write first, then typeset.
