We all have different reasons for selecting the plugs we select.
Way back before Warren Johnson get a DElco sponsorship he liked to use the Champion plugs, which at the time many considered them to be Mopar plugs and didn't like them. What he wnted in a plug they provided. That was the Champion offered several varying heat ranges in-between what was offered by any other plug company. He ran pretty good. After he was sponsored by AC DElco he began using the AC Plugs. He ran pretty good.
After Jim Ytes was picked up by Split Fire as main sponsor he used only those plugs. He ran pretty good.
When Bob Glidden was racing and sponsored by Ford Motorcraft and later Autolite, he ran those. He ran pretty good.
A lot of nitrous racers love the NGK. A lot of nitrous racers love the Autolite.
What you do not want in a racing engine is a resistor sprak plug.
So to give you an answer that will not answer your question;
Any spark plug that is capable of bridging the gap between the conductor and the ground electrode at the cylinder pressures needed and with the fuel used.
If the plug works well with the engine and is the right gap for conditions and right heat range you will not find a nickel's worth of horsepower difference between the brands.
