We are trying to differentiate ourselves with the table of contents on the right. It's hard to tell when you start (because there aren't many pages) but the tree-like Table of Contents (with drag and drop) is great for larger sites.
Our staff site, for example, has over 100 pages but is nicely organized. The software can support 1000 page sites. Probably more but we haven't tested performance over 1000.
