I'm surprised to see not enough mentions of Emacs's Orgmode which clearly dominates Vim when it comes to note-taking with or without Latex. Not to start another Vim vs Emacs war, I've been using both of them for quite some years now for each of their specialties. But when it comes to Notetaking, Orgmode is hands-down far superior with it's rich plugin ecosystem & minor modes within. Some plugins I use to do Latexy stuffs on Emacs is (ofc) Auctex, latex-preview-pane, PDFTools. Finally, OxHugo to export my Latexy org as a blog post to my Hugo blog.
