It used to be that the editor wars were vi vs. emacs. Now we've evolved to the point where it's the text-based editors (vi and emacs lumped into the same camp) vs. the graphical-based ones (sublime and all the rest).
I've never used Sublime, but a few people in my office use it, and I'll admit, it looks pretty neat. If I was editing files exclusively on my desktop, it might well be what I would use (and I say that after 30-odd years as a die-hard emacs user). But, the biggest problem I see with Sublime (and I'm assuming the same for rest of the graphical editors) is that it doesn't work and play well in a cloud environment.
We do all our work on servers in a hosting provider. My desktop is just for reading mail, browsing, and hosting terminals windows. And maybe, as I get dragged kicking and screaming into gmail, that list might get reduced to just "browsing and terminal windows". All the files I want to edit are remote. I've got my terminal program configured so one click gets me a shell connection on a remote machine, then I run emacs (in text mode, i.e. -nw). All my files are there.
I watch my office mates who use Sublime struggle with moving files back and forth. Drag a file down from the server to their desktop. Edit it in sublime. Push it back up to the server. There's some kind of integration which takes much of the drudgery out of that, but it's still pretty clunky. Even if you used something like sshfs to mount your remote directory, it's still a lot slower (I'll often grep 100's of source files to find a function name; that would be deathly over sshfs).
Yes, you could run the sublime app on the remote machine, talking to the X11 server on your desktop, but that's pretty horrible in its own way. It does solve the problem of getting the editor close to the files, but U/I performance sucks over most real-life networks.
I will admit that the idea of customizing/extending my editor using elisp is just frightening. A cool idea 35 years ago, but at this point, it's absurd. I'm glad that there are still a few lovable fanatics out there continuing to maintain the language bindings I use, but it's clear that's at an evolutionary dead end.. The fact that Sublime uses Python is one of the things that makes it attractive.
