Good reviews verge BUT <---- notice the big but!

I was just reading "THE BEST PORTABLE BLUETOOTH SPEAKER YOU CAN BUY" by David Pierce.

I am not sure what I read so any clarification would be great. Is this an opinion or a review? If it is an opinion, then I am not sure why there is a scoring system and points are awarded or deducted for a particular feature or shortcoming?

If it is a review then the structure suffers from giant shortcomings because it is not awarding any points for specific high points or low points.

The article should have created categories such as
1. Feature base
2. Sound quality
3. Connectivity
4. Compatibility
5. ruggedness

(amongst other categories)

Each category should have its own scoring system with the winner having the aggregate as the justification for placing first. Why is this important? Because many users don't prioritize the same way as the author. And the reader would get a much more clear understanding of the article and its conclusion. If the purpose of the review is to enable the user to determine the best outcome applicable to their own circumstances, then the article's structure fails miserably. But then if it is an opinion piece why is it attempting to come across as a review?

I have wanted to make this criticism for a while now as the format between opinion pieces and reviews seem to be blurred a great deal. /rant
