The thing that would get me to use Emacs is a plugin implementing Neovim's remote editing protocol. Vim is an incredibly deep state machine, and no plugins that reimplement it get things exactly right.
You can do remote file editing with local editor setting using Emacs TRAMP which when used with SSH profiles treats remote files as if they were local files.
If you love modal editing, as I do, you can use EVIL mode to emulate Vim quite well. I used Vim for years and switched within a month, most of the transition was in getting used to all the tools built into Emacs. Movement was identical, even things like text objects and Vim-surround work well.
The quality of Emacs packages are very high and almost always “just work”. And when you do have to read the documentation it’s very easy to find and understand.
By "remote editing protocol," I meant the Neovim RPC API which allows other editors or tools to run a Neovim server and get it's exact behavior, keystroke for keystroke. It's been a few years since I tried EVIL, but last time I ran into behavior differences within fifteen minutes (something about pane management? It's been a while). I don't want "almost exactly Vim," I want, "literally identical to Vim," as a starting point.
Sublime Text has a plugin which implements the API; it runs full blown vim plugins.
I hear good things about evil-mode & viper for emacs. Dunno about Neovim's remote editing protocol though. TRAMP does the trick exceedingly well for me (to include 'remote' editing as root on the local machine, which is kinda awesome).
I have tried evil mode many times. It just doesn't work. It may be 99% faithful implementation of vim but I hit the missing 1% so often that I throw up my hands before quitting out to use the real thing.
