I'm a researcher, and I have a git repository for my notes, which I edit using markdown. It supports latex math, tables, cross links, labels, and html if I need to do anything fancy, like inserting images, videos, etc. (youtube embedded video? no problem). I can edit them from any device, and they get sync'ed everywhere via git.
I can also read them from everywhere, and markdown renders super nicely.
I take markdown over org-mode everyday. I used to use org-mode 15 years ago, but today that's pointless for me.
