org-auctex VS obsidian-tikzjax

org-auctex: Async LaTeX preview support for Org-mode using AucTeX. Mostly deprecated since Org is getting a new async LaTeX preview system.

xenops looks quite interesting, I hadn't seen it before. I do also render my LaTeX maths in org, though with org-auctex instead of the default org-latex-preview (much faster!). The workflow is mostly that I write some maths inline to org, not inside of any source block—much less noise. When I'm done with a particular piece of code, I simply rerender the whole buffer; org-auctex is fast enough so that this doesn't take very long, even in dense org documents. The SVGs are automatically unprettified whenever you are inside them, so editing is seamless.

You can use most of the functionality of that blog post inside of Org. Things like cdlatex even have a special org-cdlatex-mode in order to be as unintrusive as possible, and for fast previews there is org-auctex (from the same author as the above post). Certainly things like autoexpanding snippets and other goodies work without a problem in Org.

Just a note that latex preview support for non-file-associated buffers (including elfeed/shr buffers) is still planned for org-auctex. (Time for Emacs has been really scant this year!)

For smoother latex previews in org you can try org-auctex. It's not done yet but I find it to be a big improvement.

In Obsidian you can even have Tikz diagrams by simply installing a plugin: https://github.com/artisticat1/obsidian-tikzjax

There is this Obsidian TikZJax community plugin, which supports pgfplots among several packages: https://github.com/artisticat1/obsidian-tikzjax
