Best plugs for 89 Mercedes 420SEL ??

Price being no concern, what are the really best plugs to buy for an 89 420SEL ?? I know the W8 DCO is the top regular standard plug for this car, but is it better to use the Quad platinum plugs for the very best overall performance ?? Please advise .... getting plugs in the next day or so.
Thanks, BC
