I use atom-vim as well as the full suite of extremely flexible key-bindings and I am FAR faster in Atom then I was in native vim. Not only that, but the plugin ecosystem is more suitable for my needs, more hackable, and more modern. As a JavaScript developer, Atom has totally recharged my workflow.

One thing that does need some love is tree-view; I sorely miss the full functionality of NERDTree (paging, text search, etc)
