At one point I looked at them all. They are all very primitive, but
that's a good thing. In the end, I made my own because I didn't care
for the specific mix of functionality nor/or their coding style. I
wanted hierarchical pages, friendly urls, templates in the DB, rich
text editor with the ability to use template tags, global content
blocks, a generic article system for news or blogs, and syndication
support.
Thing is, it is so easy to build a CMS in Django, that you might find
it better to write your own, particularly if you want to customize it
to your liking later.
