I found this link, it has a feature comparison tool for several Wiki's.

I use and like MindTouch's DekiWiki (www.opengarden.org), mostly because
of the GUI editor for pages. I also like their general look and feel.
Although I am not so enthused about their use of mono, and it does
require a mysql database so it is not light weight.
