Not that great in my experience, good enough to read and navigate through org files, but lacks many features and has performance issues. vimwiki https://github.com/vimwiki/vimwiki is probably the best note-taking plugin for vim.
I've been using vimwiki daily for the past month after I saw it mentioned here on HN. It's really changed a lot and has replaced the method I had before that involved VScode markdown snippets. It's nice to be able to directly link between my diary / task lists and my general knowledge base that contains code snippets and information about my projects, etc.
i am still trying to figure: how is that any better than having the stuff as indented text, or writing it downs as markdown?
