Another selling point was the ASP.NET control library they offer which made development much quicker. I also chose the developer license to get the full Flash source code for some custom modifications. One last cool feature is the chart builder at http://extra.amcharts.com/editor/ which makes visualizing the charts and generating the settings file a breeze. Charts like this can really add some “wow” factor to an application. They have an active community forum, plenty of documentation, and a helpful staff so check them out.
