I made the jump from Vim to Emacs about 6 months ago and org-mode was a major reason. It is very much worth it IMO. Evil supports all the Vim commands I was used to, and org-mode has been a revelation. It gave me that one place to put all my tasks, meeting notes, brainstorms, etc, and with useful workflows for keeping it cohesive. It took me an afternoon to get Emacs set up as my daily driver. It took longer (weeks/months) to dial in my org-mode workflow and knowledge to a point where I was satisfied with it, but org-mode was still a net improvement from day one. I continue to discover cool features in Emacs and org-mode on a regular basis. Don't wait, try it!

Spacemacs makes the transition nearly painless, I'd highly suggest it.

Have you tried https://github.com/jceb/vim-orgmode plugin?

There's really not much to learn!

I switched from vi/vim to emacs just for org mode. Took about a year but now I can't see going back. Its not that bad, and org mode is definitely worth it.
