I'm a heavy user for a vim for the last few years. Is emacs worth checking out to potentially switch to? Or should I just stick with what I'm already productive with?
If you care about integration with other text-based tools (like email, instant messaging, source control, code review, IRC, ...) then switching to emacs will transform your workflow.
There are a couple of emacs modes that stand out, and in my opinion make emacs worth it:
* Org-mode (https://orgmode.org): A note taking system * Magit (https://magit.vc/) the best git client I've ever used.
