Our Minivan would eat semi metallic pads every 30K, switched to ceramic and haven't changed them since. 60K + miles. Started using them on all the DDs in the family.
They stop great and do not make a mess on the wheels like semi metallic.
To counter the rotor wear argument, when I didn't catch the 30 k interval on the semi metallic, the rotors got chewed on, and here it he rust belt the rotors actually get some nasty rust rot on the surfaces requiring replacement anyhow.
