I'd go with NGK's...everytime I've switched from an Denso to NGK plug the overall performance was objectively superior and 7 people that have trusted me to work on their bikes or cars have noticed it also without me mentioning the switch to eliminate the placebo effect...but since they were all within 60 miles of each other I can't say these results will be consistent across the globe.
