Which wysiwyg editor works best for Drupal 5?

indeed I finally figured out that FCK seems to work (fingers crossed),
but for me only if I disable it by default and leave it only as the link "rich text editor"
which is afaik a global setting - I would have liked being it "on" by default for all users
but have it "working" (i.e. disabled) for the admin who needs to fiddle with PHP
(none of "my" "normal users" know what "rich text editor" means and they could not guess that clicking on that button opens a second window where you do a "parallel" edit of what is already displayed in the main window... - I think also for other "normal users" this is awkward)

Also, I have nevertheless big problems : if one < p > tag is not well closed or
some tags (like < b > overlap or so) (which quite often happens when copy-pasting
from IE or Word into the editing form), then often various portions (up to 100%) of
the code will disappear (sometimes you can save it but if you do preview first, then all is lost)

i.e.: robustness / tolerance w.r.t. imperfect HTML code = nearly zero. (imho)

Conclusion : FCK is maybe the best (?) but far from being satisfactory.

I'm in a similar position. I'm test driving a raft of open source CMS' and there are, as we all know a few. Drupal's a nice CMS and years of work really shine when it comes to the user, roles, taxonomy and the various other infrastructure tools and admin. Most powerful. Few other CMS's have such a straight-forward admin approach and the CSS is easy enough to radically transform the look. If your wanting to present plain text and links in a CSS manner this totally rocks!

The one area, I've personally felt, that is just that bit lackin is the 3rd party/inline content creation. I'm expecting to let non-technical people publish articles from all over the company and being an animation studio we'll be needing the requirement of being able to show images and movies. This is something that no doubt can be plugged in as a module and out of the box basics are great to build on. But when we're using internal tools which offer wiki like abilities (and it took time to get them using the inline editor on that properly) our staff will be somewhat bewildered by the basic/missing-items premise that they've became accustomed to.

I'd love to manage our site with a drupal backend. It's one of the few that's got a powerful enough engine with so many great set of features that I would happily use it. But it's the content creators who make the decisions, and I've plugged in TinyMCE, FCKedit and a couple of image modules and sadly it's not for us.

Tis a shame, I know what effort is needed on an open source project like this but there are others which sadly fit our bill better on the content adding front. I'll be back and regularly checking out the new releases, I'm hooked for sure , but there are some real advances being made on other CMS backends which promise and mostly deliver.
