I like the NGKs. Started using them on my dirt bikes years ago and they seemed to be the most dependable. Hardly ever fouled a plug compared to my buddies autolites that were always fouling.

 

I've never had great results with Champions until I got a Jeep with the 4.0L engine. "High perfomance" plugs like Bosch platinums just didn't seem to work well with this engine. Following the advice of the masses on the Jeep boards, I switched to the Champion Truck Plug which has been stellar for this application. As for my Fords, I've always used Autolites or Motorcrafts with fine results.
