I was personally impressed by the slickness of the interface, and by the fact that it has been designed to scale well to large websites. The developers have obviously thought carefully about the architecture, and are aiming for the "CMS plus web platform" approach of Drupal. I was also personally impressed by the responsiveness of the development team, their willingness to work in the community, and the clarity of their vision for the product. Worthy winners. Give it a look.
