Not sure how you find crashing acceptable. Something similar to Atom.io is Visual Studio Code. Here’s the Elixir support as well.
I personally use Spacemacs (emacs and vim combined).

Because compared to my home linux desktop that is rock solid, my Windows work computer is anything but stable, so I just expect it. 
Hmm, I’ll look at it.
Heard of it, never used it, can it really seem vim’y or is it like the poor evil mode in emacs that lacks way too much functionality? And does it work well on Windows?

I miss nothing from Vim proper in Spacemacs.
I have it installed on my windows computer and it seemed to work well. I rarely use that computer though, in fact haven’t turned it on in over a month so I can’t attest to how it works at the moment.

This forum has a wiki for Spacemacs.
I tried Spacemacs on Windows and it worked for me (but I use it on Debian nowadays). Instructions.
It’s better than the typical “evil” mode. Does a lot more. Give it a try… doesn’t take too long to set up. 
Edit: You should use it with Alchemist (never tried it on Windows though).

Just a comment - - use emacs without evil mode on Windows. Very happy with Alchemist. Plus there’s a Powershell major mode that is really pretty nice on Windows.

I’ve been learning Vim and using vim-elixir. I used SublimeText for a long time with JavaScript but now with Elixir I switch into IEx a lot when I’m coding, so it’s easier to split panes in my terminal (OS X) using Tmux and work that way.

Currently using atom but have been learning space macs.
I did use ruby mine for a while for ruby.
All my java is done in IntelliJ.
