Personally I'll take the soft, good, smooth, quiet, pad eating, brakes anyday over the rough, heavy pedaled, screaming, pulsing, grinding rotor eating hard pads.
If you like that, drop down to M*d*s and get some of those pads guaranteed to scream for the rest of your life. But remember the calipers and discs eaten up are never warranteed anywhere that sells that crap.
