[Zope] What would it be your preferred basic Zope installation?

I'd like to have an idea of the most used products (therefore recommended) by the community, in order to try them anytime. Although maybe many of us don't need them yet, it's always a good idea to play around with the tools preferred by others, after getting to know how helpul they found them, associated to their features and particular use cases. I think I'm asking for an up-to-date product rating, and that's why the question is proposed as this: What products would include your preferred basic Zope installation? Thanks in advance, Ausum
