If you're currently a vi user, I'd recommend spacemacs (https://www.spacemacs.org/) to soften the learning curve. It comes batteries included (as opposed to a stock emacs install which requires a _lot_ of customization) and uses evil mode (vi keybindings) by default. You can expose yourself to more and more of the emacs way slowly.

Also emacs is largely self-documenting. Learn the keys for querying documentation first thing. You can search for current keybindings, what a given function _does_, etc all live while you're using it.
