I bought most of these website creation products ( I also use ASP solutions lik weblogs for different purposes) and used them for several websites. I think Sandvox stand outs from the competitors in having a different approach, making it rather flexible and in the Professional version also rather easy to go beyond the boundaries from a product like iWeb or even Rapidweaver.

Where they differ is especially in using in flexibility and Pagelets, they are included and free. I know most of these are also possible to add in Java-scripts but here it's like drag and drop and very easy to adjust.

Also interesting is the possibility to include Google's; Site verification, adding a Google Sitemap and also automatically adding code for Google Analytics.

The site, a travelsite (http://homepage.mac.com/hpkok/sv2007/) I made, also incorporates an Amazon list of travel books for the countries or regions. And again very easy to add or change.

I do have a remark though. The included templates are not so interesting to my opinion. I used a commercial one from Blueball Design, which is more professional.
