The content above is 98% unique according to Spin Rewriter and I really like it. It actually seems better than the WordAI spin – only the “Standard” one however, it is no match for the “Turing”. One thing that the spinner failed to recognize is the “green eyes” phrase where it replaced it with “environment-friendly”. Yea, I laughed too. Anyway, here is the spintax for those interested in more testing:
Think of it this way: What do you have more chance of hitting, a distant, tiny target or the broad side of a barn? For the sake of search engine optimization, you want your website to be the broad side of barn. The more quality articles, or unique readable content, your website or blog offers to search engines (and therefore the general public) the more exposure your website will receive from major search engines.

Spinning Speed – How quick can these spinners spin the article above. WordAi took 3 minutes and 48 seconds and SpinerChief III Ultimate using Super Spin in the balanced setting (meaning try to be unique as possible while still being readable) took less than 3 seconds to generate. I’ve had WordAi take 5+ minutes before, they need to speed things up. Clearly SpinnerChief won the speed test.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
