I tried out Helix, but I think the biggest issue that I have is that with (neo)vim, I can use the keybindings in most of the editors I use through a plugin (such as IdeaVim for the JetBrains suite) - but I do not think the concept of Helix keybinding plugins have really hit anywhere.
Helix itself seemed really cool when I was playing around with the tutor mode though.
