They do perform better under hard circumstances but it depends on what you want. They take a little longer to reach operating temperature, wear faster, more brake dust but they will stop better and handle heat better. But they are more expensive and don't last as long. You're going to have to balance performance vs daily driveability to your needs.
If you really want some all out performance, sick stopping power and a pad that will still perform great under heat that will melt the seals out of your caliper......behold the Porterfield R4-E 8)
