+1 for Spacemacs. Former vim user, now using smacemacs for past few months.

I found a number of things just work way better in emacs than in vim. For example, web-mode was a revelation for me. I could never get vim to get syntax right in mixed HTML-JS files.

Ability to edit very large files with ease was another one in favour of emacs. Vim would freeze up for a seconds or two while saving even half a megabyte file.

helm and family blew my mind away.

Another win spacemacs is it does not hide default emacs functionality. All default emacs keyboard shortcuts would always work, so learning vanilla emacs is still helpful.

Once I got to know spacemacs shortcut layout, it was surprisingly intutive.

(YMMV)

I know this is going to sound silly, but I'd go so far as to say that Spacemacs is one of the best editors ever made.

But it's not nearly as portable as vanilla vim. Even vim with several plugins, including vimproc and Unite, I've found is a lot more portable than Spacemacs. Spacemacs is a lot slower as well.

For me, unfortunately portability is really important, which is why so far nothing has been able to sway me away from my trusty tmux + vim + Unite combination.

I've picked it up three times now, and every time the plugin combination I chose (nothing outside if what's included in Spacemacs, and using a fully supported install) would lock up the editor while using full CPU 3-4 times a day.

The minor upgrade in functionality wasn't worth the instability.

I've tried Emacs + Evil and Spacemacs, but eventually just came back to Vim.
