I had always found Champion spark plugs to be more reliable and longer lived. Though, that wasn’t under test conditions, and over 60 years ago. My first instinct today would be to at least try the old reliable.
Some variables that you hadn’t mentioned, but do bear directly on your results, include:
(1) Manufacturer’s heat range: Manufactures recommend specific spark plugs for specific engines. Sometimes they recommend different heat range of plugs for different working conditions for an engine. I didn’t hear you mention whether or not these were the recommended plugs. Maybe I missed it?
(2) Plug gap: Each engine and spark plug manufacturer has recommended gaps for their electrodes for each application. I didn’t hear you mention that, nor see you test and adjust for it.
(3) The square, corner edges of both the center and side electrodes should be sharp, clean edges. Since you used new plugs, one should be able to assume good, sharp edges. Problem is, that may not be a good assumption. Double checking prior to installation, and filing off rounded edges where spark jumps from and to can sometimes make a difference.

Metals corrode by oxidizing. It is reverting to its original ore. “The definition of corrosion is: metal, returning to its natural state.” Once we know that, we know that all metals, except gold, will corrode through oxidation. We cannot stop it, but we can slow it down.
Aluminum corrosion is aluminum oxide, or ALOX. ALOX is an abrasive; a very good one, as it turns out. Much of the sandpaper that we buy says “ALOX” on it.
If an aluminum carburetor corrodes, it produces that ALOX. That carburetor is the one thing that sends both fuel and air into an engine. If the carb has corroded, it will then deliver a great abrasive to the working parts of the engine. Nice, huh?

I do not have any hard evidence to either charge, or defend the Dyson Company. I do have a strong suspicious opinion, though. In my life, I have yet to discover a competitor who charges that large of an increase in price, and delivered a product that was that much better.
Mind you, I’m not saying to buy the cheapest sample offered. I learned that lesson at about 14 years of age. I’m saying that a similar object that has an asking price of, say, 200% to 400% above market price range is likely to be highly, suspiciously, guilty of snob prices.
Some people will buy it, others won’t. In a free market, both manufacturers AND customers are free to make their choices on quality, usefulness, and price. I’m in favor of that procedure.
