Every time I see something about org-mode posted, I get mad FOMO and decide to re-dedicate my life to learning emacs and everything it has to offer. Then a little while later I inevitably drift back to vim.
It's getting to the point where I need to just ignore cool stuff like this post in order to get on with my life.
For me it seems to be down to the following. When I am working with vim, I feel like I am in the same eco-system as my shell, there is a really nice continuity, whereas emacs feels like a separate entity (almost like I have an separate instance of a word processor open). I am aware emacs can be run in the shell without its GUI, but it still felt like it was separately sitting its own world.
For org stuff, I now use taskwarrior [1], which embeds into vim using taskwiki [2] and vimwiki [3] (which provides markdown export)
