I'm after (short) opinions on FCKeditor vs TinyMCE and whether either or both are XHTML compliant.
In the interest of keeping with the spirit of stackoverflow, if someone has already made your point, just upvote them.
From my experience FCKEditor does indeed produce XHTML compliant code, but that code is slightly different depending on what browser you're in. Mostly, this was related to the enter key producing either a break or a paragraph, and I think it may have been configurable.
