YouCompleteMe, a Fast, As-You-Type, Fuzzy-Search Code Completion Engine for Vim
I want to see developers who are experts in IDea, emacs, vim, etc. face off to code a variety of projects in several languages/frameworks side by side in each editor/IDE so we talk about the empirical differences. vim is a lot faster for many things, but I wonder how well it compares when you need to debug Java remotely (in a container on another server), for example.
