I also just use Vim to write markdowns, but without any markdown plugins (beside the built-in markdown syntax highlighting in Vim) and I compile the document to pdf manually using Pandoc. I rarely need to write markdowns though, and my usage is not advanced at all (like to write simple writeups that sometimes require maths and code blocks, which I only use for myself). So Vim + Pandoc is enough for me.
