I have tried tons of editors, and I always come back to vim. Heck, I have even moved my .vimrc to be the simplest possible with the smallest number of plugins.
For instance, notepad is default on windows, and I'll use that when needed on vanilla windows machines, but for the 99% of my editor needs I install and customize a number of enviroments (including Vim). I don't mind whether it's installed by default or not.
I know this is an issue where I work. We have 40 thousand plus servers, and we aren't going to have everyone install their editor of choice on all those machines. If I have an issue I need to check on a server that requires some text editing, I have to use one of the default editors.
There is actually this neat hack you can use(if you use VIM) with rsync.

I know it's kind of Hacky, but the performance improvement is worth it IMO.
I normally just use TRAMP. For those who've not used it, it's an incredible little emacs package which gives one a very Plan-9-esque feeling, in the sense that all the different systems one connects to feel like one whole.
As an example, when one is editing a remote file shell-command runs commands on the remote system, and of course find-file and friends work exactly like normal — only looking at files on the remote system.
I glanced over much of the presentation, and none of it was about the editor itself as a user would see it. I'm impressed and glad for the technical investment, but to be even a consideration for a replacement, I need a focus on how it's supposed to be an improvement, not just a substitute, for vim.
