I prefer the semi metalics in the Posi Quiet version. Iuse them on the SRT6 & SRT 8. Very happy with them.

Wow! I didn't know it was the same manufacturer. Posi Quiet also comes in semi metalic. Semi metalic should give a little better braking but they are also harder on rotors. When I switched to Ceramic, I didn't notice any difference in braking from the factory duster pads. The ceramic pads have proven to be very gentle on my rotors which are original with 61,000 miles.
