I hate the built-in WYSWIG editor for WordPress. (EDIT: Editors of the sites I support hate it, which in turn makes more work for me. Hence, I hate it.) I know there are some alternatives out there, but I'm curious what the more functional and usable ones are?
Issues that I hear:
The text auto formatting either a) adds html or b) strips html. This is annoying.
The view within the preview section doesn't use the stylesheets of the web site itself, so it's not really WYSIWYG
