If you are looking at tire rack ratings (and other tire shops), you must read the reviews to filter out the chaff. There are often excellent comment there by drivers that know tires.... along with nonsense. The test are also decent, but you need to read them from your POV, which may be different than the author.
I have never been led wrong by info on tire rack, except for being a bit disappointed with the general grabber wear, which everyone raved about three years ago.
