I don't know what they mean by 200%, but E has the best crash handling of any app I've ever seen -- where any other desktop environment crashing would send you back to the login screen, E pops up a menu allowing you to attach a debugger, or you can just click "continue" to re-launch the WM and have it pick up exactly where it left off (in particular, remembering which windows are attached to which virtual desktops and stuff like that)
