I'm a fan of MarkitUp + Textile, nothing more, it seems users likes it once they get used to the simple textile syntax. I'm against wysiwyg javascript editors, they tend to add a lot of overhead over the web page. The only wysiwyg editor i could recommend is WYMeditor (.... even if it isn't really visual editor).
