Last spring I was changing the plugs in about 10 of my (
old and depreciated) cars, Porsche, Audi, VW. After doing some searching I ended up getting Denso Platinum TT 4504 (PK20TT) "Made in Japan". Lots of them, going into a wide range of engines. There was not an increase of 10 HP per plug, and I didn't get 50 miles more per tank of gas, but nothing has blown up and everything still runs smooth.
I'm still fairly simple when it comes to maintaining cars, so I'll call the them my current favorite: Versatile, not silly expensive, cars run smooth and engines don't blow up.
