I have always used the "upgrade" carbon-metallic pads when I've used local parts shops for brakes pads (as opposed to specialty shops for race/track pads...)
That was until I got my Gen4 Taurusaurus and had to replace the pads/rotors. This time I bought the ceramic compound pads and I won't use anything else in the future! They are definitely worth the extra $$$.
They bite harder initially, don't need to be bedded-in and don't fade. MUCH better than the standard pads.
