The problem is that there is no "best", not even for the typical consumer. I speculate that those speaker brands listed may have paid to be included in the list, and the author did not bother listening to all of the speakers in the list, let alone compare them, in a listening test, to other comparably priced speakers in their categories. If my speculation is correct, it really is a disservice to consumers.
But, nothing new. It has been going on in the audio industry for decades and decades. Cryogenically treated power cables for anyone?
