My year subscription of TBS is renewing in a few weeks. Honestly I am a happy user of TBS but I did some research and there seem to be mixed feedback on how content rewriter or content professor do a better job. Did anyone did a real personal testing on these tools? Do they work better than TBS? If yes in what features? I don't really mind the prices, I just need to get the spinner that does job the best. Any feedback is highly appreciated. Thanks.
