To second zdubyadubya's experience, there is no difference in performance under daily driving and very little if any under aggressive driving. The only difference is they do squeak in cold weather. My dealer never got around to installing the high performance before I bought it (Oct 2020), so I went through my first winter with the stock street pads and put the high performance on later that spring. This year, as soon as temps started to get below 45ish in the fall, they started squeaking.
So in conclusion, no, I personally don't think they are worth the extra ~$600.
