title: Most widely-used Drupal rich text editor plugin?
body: <p>I'm looking to set up a JS WYSIWYG editor for my clients' Drupal site.  </p>
  
  <p>What is the most popular Drupal plugin for this, that also supports uploading images through the editor?  I'm new to Drupal so I don't know if there's a <em>de facto</em> standard or not, and Drupal's plugin browser isn't very helpful for gauging which one is best.</p>
  
  <p>I will be testing <a href="http://drupal.org/project/ckeditor" rel="nofollow" title="CkEditor">CKEditor</a> today.</p>
  
  <p>I have looked into using TinyMCE but some of the features seem to be pay-only; which at this point is not <em>un</em>-acceptable but if a free alternative works better I'd rather use it.</p>
