Drupal 8 developers, as a whole, are a bit gushy about PhpStorm. I use it; it's useful. But a decade and a half of my programmer muscle memory is Emacs keybindings, so when I use a different tool than Emacs, I feel like I'm trying to cut vegetables with a mallet, or write with a wad of chewed gum. And yes, PhpStorm ships with an Emacs keymap, but it's just not the same. It's not only a matter of the PhpStorm Emacs keymap being less cared for than its Vim cousin. It's that PhpStorm does not support M-x butterfly.
