It lets you move, resize, and tile windows easily with just the keyboard, and you get a better Cmd-Tab that switches by window (though unfortunately it binds to Alt-Tab by default, and I haven't figured out how to override that).
I think it's better than both Divvy and SizeUp.
Also, +1 for vimperator and Quicksilver.
