I use NGK. They are cad plated which makes them easy to read on the first hit. Made it's quickest pass ever last fall on 2 year old plugs, 9.12@147

I have used Autolite and NGK plugs and the performance was the same with both plugs. And both seem to last about the same amout of time before I pull them to clean which is about a year. Ron

BCP6ES NGK is what I run, they are shorter and give extra clearance .
