A New Alternative to TinyMCE

I came across a post on the Web Resources Depot today referring to a new (to me, at least) WYSIWYG editor similar to TinyMCE. However, this new editor, known as MooEditable, uses the MooTools javascript framework rather than implementing everything with its own libraries and frameworks. It appears to be lighter weight than the full TinyMCE package, but I’m not sure how it compares in functionality.

If you’ve tried MooEditable, please let me know what you think. What are your experiences? How does it stack up against TinyMCE?
