I've been using Amethyst [0]. It works, is simple enough to configure and get started and has most things I need.

I found the default shortcuts to be the wrong way around for my cognition so I swapped them but otherwise it's been good. I mostly use the fullscreen (usually for the laptop's screen) and "3-column with main in the middle" layouts.
