I like how primary the interface is and the clear delineation of hierarchy.

You can preview how a project looks in development before pushing live. This means you can get other opinions along the way. I also like that it has version history so that you can revert back to a previous version easily and quickly. The file system set-up is well done. You are able to keep projects together by folders, with images, documents, pages all collected within the folder. This allows you to produce essentially small websites of category within your main website.

I like how Cascade centralizes content in XML and opens up transformation via XSLT or Velocity Script. I like the power offered via Velocity Script since there are Java standard methods and multiple built-in tools. I like also having capability of building tools in the CMS, including jQuery-based web service calls using the REST API.
