Copper is a better conductor than platinum.  For one who is
looking for every last tenth copper is the way.  They're also
cheaper to replace if fouled while dialing in fuel maps for
example.

Platinum plugs are for increased longevity.  If every last tenth doesn't
concern you or you don't want to change your plugs often (~10-20kmiles
for copper) put in stock NGK platinum plugs.
