org-auctex VS org-auctex

org-auctex): An (experimental) package to reuse AucTeX's preview-latex library for latex previews in org-mode. Org's preview system is terrible for previewing math heavy documents (which your org files appear to be) since it fires off a latex process per fragment and is synchronous. preview-latex uses a single process, is faster and works (mostly) asynchronously, so I prefer it for org files.

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.
