Can only talk mtb and my aim was more about vibration..having said that..I found the metallic pads to be more on/off, direct bite, more braking power. I found the resins to be more linear or "soft" for on/off. Braking power was still fine, could lock the brakes. Did have somewhat less vibration but the ultimate issue is frame design in my case. All in all, I put the metallic pads back on ultimately.
