I don't think this is a fair criticism.

1) The step where you evaluate "how they perform" is necessarily subjective.

2) you could design a study and recruit participants but that isn't something a blogger is going to do.

3) He does link to polls where people agree with the idea the result have gotten worse. Yeah, there are sampling problems with a poll, but its better than nothing.

In this case especially, the writer is answering the question: "Whose results are best according to my tastes?"
