This is obviously another spinner chief started post. Oh, well, but in my opinion having used them both, none of them would give you intelligently readable original content. The real spinner in TBS and SC is YOU. Both of these software will dish out gibberish when you simply drop copy and hit spin. To get readable content you have to spin it yourself, using TBS or SC. I personally prefer TBS because their synonyms are more relevant to the content you're writing. I also like TBS's interface, especially the newly redesigned and recoded V.3.
