The core concept of emacs, for me, is Lisp; that it's always there, an M-x eval-region away in any buffer, that creating new commands and altering existing commands is utterly trivial. I wouldn't give that up when moving to another editor.

I find helm much better than ido for most purposes. I couldn't live without helm-git-grep - it's how I navigate everything. I even add all my installed gems to a git repo just so I can use helm-git-grep easily when browsing / debugging 3rd party code.

I've gone through maybe 6 editors and IDEs in the last 20 years. I wish I'd started using Emacs 15 years ago instead of 15 months; I'd have wasted less time configuring keystrokes, and be more cumulatively productive.
