Today I stumbled upon a WYSIWYG comparison by Peter Krantz who compared a whole bunch of WYSIWYG editors using a test-case.
By the way: this is a software-index of WYSIWYG editors ...

About WYSIWYG editors
Re: About WYSIWYG editors
I must say i've been pretty happy with FCK. Def better than the TinyMCE CMS used to have. All of the high scoring editors on that site are commercial too which makes them of little use for distribution with CMS. Useful comparison though and I suppose some people may want to pay to use a commercial editor with CMS.

OK, the CMS integration is in moment not so completely like FCK but it's very easy to update TinyMCE CMS module to current TinyMCE version - you must only replace the TinyMCE directory with the current archive from version 2.0.5.1 .

I'm very fond of the FCK editor and especially the additions that were made to easily integrate internal links and news etc etc.... Love it!
