On the plus side, your comment does contain some specific observations which could have made for a good comment—one that communicates interesting information respectfully. If you'd please post that way in the future, we'd appreciate it.
It's funny, when I saw the title I was hoping the article would include some sort of blind ranking, where you could see the outputs (without knowing which model they came from) and score them on some criteria. Could have been a fun way to get a better ranking of the results.
