I don't think you've mentioned a single thing that can't be done by Emacs/Vim, with minimal customization. Personally I use Vim, which has great auto-completion (it's minimalist and extremely effective), extremely customize-able code-folding, highlighting and advanced navigation features out of the box. With a few plugins (like the NERD family, Syntastic etc.) it has all the features you mentioned, along with having insanely good performance and integration with the shell. And that's not to mention the advanced editing capabilities it has for managing text, which far exceed those available in editors like Sublime.

I've never experienced this "insanely good performance" from Vim or NeoVim. It's fine for editing code when lines are short, but as soon as the lines get long or the file itself it's long, or if I'm using all of those plug-ins necessary to replicate basic functionality in Sublime, it slows down substantially.

That said, I can't let go of modal editing, composeability, and word motions. Here's to hoping sublime implements them and I can relegate Vim/NeoVim to quick fixes in the terminal and Git commit messages.
