Matt thats really interesting you feel that way.
I've used only NGKs in all my Bikes, Cars and Outboards for years.
In the past I've had a Champion plug that gave up after just a couple of hours in one of my Hillman Imps, and another Champion plug that was dead straight out of the box for an old Chrysler outboard.
A full set of Bosch plugs I put in my Bike made it run really uneven, and swapping back to NGKs sorted it out with no other changes.
