Sharepoint Server or Community Server

Hi All,I need to create a community website.I have two products in hand - Sharepoint Server and Community server.Though microsoft promotes its our product - Sharepoint- for making communities,forums,document library etc, its own websites like http://silverlight.net , http://asp.net etc are created using Community server.This leads me to  the confusion of whether to use SharePoint Server or Community Server.Please pour in with your opinions/suggestions/experiences on drawbacks/advantages of using one above the another
