Thanks for the pointer. I do have seen that before. But I think it's not difficult to see the difference. First of all, they are maintained by different people with a distinct goal. SpaceVim is aiming to serve a counterpart to spacemacs, which more suitable for pure vimmers, I guess. However, space-vim is intended for switching between spacemacs and vim painlessly. I'm both a vimmer and spacemacs user, and I really like the interface and philosophy from spacemacs.
