In the 26 years and almost 100,000 miles I've tried them all and for a number of years I played with a turbocharger. Through all of this I've tried NGK's. Nipondenso, Splitfire and all the Bosch Platinums. I don't have any experiance with the Nology set up but with what I've tried I'm convinced the engine ran best and idled smoothest with the original Bosch HR6DS silver tips or even the copper version.
