What kind of difference? If your plugs really needed to be changed, you might have noticed a difference with any old plugs from Bob's Auto Parts and Bait Shop. 
The best way to know if there's a difference is to put one set of new plugs in for a hundred miles and then the next set for a hundred miles. Maybe even use a dyno for each set.
Just sayin'!

performance is better thats forsure more pep in the throttle
I like Denso plugs but I couldn't say they're better or worse than some of the others.
I just changed mine last week. The oem densos came out and the NGK equal went in.
Feels like a new bike and idle has not been smoother.
That being said bike has 4000 plus miles on old ones and I had a prob with some H20 in the gas so they may have been slightly fouled a bit....
Maybe just that you put new plugs in there and the bike feels a bit better but your mind feels great.....

Before anyone gets excited about one brand over another, remember that if you replace an old plug with a new one, yes, you're going to notice a distinct difference, even if you don't change brands. This is even more true if you go too long between change intervals but nobody on here would ever do that, right?!
Seriously, though, you see this kind of fervor all the time with various products. Most notably with tires. I see guys take off their old tires all the time and then rave about the new one, different brand, yada yada.
That's why in my prior post I said that the only way you could know would be to switch brands after a hundred miles and see if you notice any difference. Frankly, the only advantage I could ever imagine between brands would be time between changes but I suspect the variance or cost savings would be minimal at best.
Just an observation!

We tested this when I was in school, swap from old plugs to new plugs (back to back dyno pulls) +3 hp across the board. Swap from new plugs to quadruple platinum iridium unobtanium magic plugs, no difference at all. Now talking tires....I've seen a diff going from crappy contental touring tires (came on my old used bike courtesy of cheap ass dealership) to pilot powers...:stirpot:
