I've found that many power users prefer the precise control that Textile (or bare HTML/CSS) provide. They really take advantage of the ability to specify floats, margins, and the like. I've tried supporting both Textile and 3rd party wysiwyg, but it just gets to be a hassle when multiple users try to edit the same thing. They wysiwyg outputs some pretty gross HTML, which the Textile users then have to deal with. Still, if all you offer is very basic formatting, then a wysiwyg rich text editor is an excellent choice.
