I thought this was the case too, but YouCompleteMe is really terrific for Vim! I wish emacs had something similar.

Have you tried company-mode?
This looks great! I can use Emacs again!! Thanks!
Haven't actually tried it, but I've come across https://github.com/abingham/emacs-ycmd before and it looks decent? I also use autocomplete-mode which has a bunch of hooks for pretty much every language under the sun. I have it set up with jedi for python and clang for C/C++/Obj-C.
Plugins in vim are usually pretty poor compared to emacs, and vimscript is frustrating. Emacs Lisp is at least a consistent language, and one that I can figure out how to use much better.
