I wholeheartedly recommend it. I was a Vi(m) user for years. I love vi as a concept, but extending it always felt very wrong and cumbersome for me, whereas in Emacs it all feels natural as it truly is the extensible, customizable text editor. org-mode and slime made me pull the trigger and kept using it for half a decade. Then I lost my Emacs config. Installed Spacemacs and never looked back. It gives you better defaults, a good community and a framework that lets you easily extend it in a more modular way using layers. It's also much gentler on my wrists. I still use nvi for quick edits though.
