With all the talk of Vim vs. Emacs, it surprises me that Emacs is in the low single digits, while Vim is 25% of all respondents. It does not surprise me that it is 40% (and #1) amongst sysadmin/devops practitioners.
I prefer Emacs to Vim, but I prefer Idea for Java development over either, so since I mostly work on java projects on Linux servers, I actually use Vim significantly more than Emacs.
