It's extremely fast and intuitive to use, middle button to drag windows to zones (or whatever you configure). It comes with some decent layout templates.

However the template system is in XAML which is fine if you're au fait with that but can be a bit fiddly to get what you want.

The only other issue I have with it is that the full version - which is definately worth the money - is distributed via the windows store which forces you to have an account with Microsoft. Overall though, excellent.
