If you mostly just want the memorized shortcuts to work, they tend to work OK in VSCode, Atom, IntelliJ and even Emacs - Spacemacs is even a better ViM for some.
As someone who did a fair amount of hacking in vimL, evil-mode is a drastically improved vim. It gets basically everything right, out of the box, and extending it isnt nearly as painful as using vimL or interacting with vim's Python API.
