[Zope] Zope Comparison

Hi, It can't be that you all are novices like me. Come on, there must be experts on this thread, who have already previous experience with other web-applications. Why don't you tell why you use Zope above the others? Has nobody used another Zope-alike before getting in to Zope? Please, help me. Only one of you responded to my question. I know it isn't a problem-solving question. But it can help me to convince other people of Zope. Thanks in advance, Tom.
