Nah. Any difference I would have "noticed" would easily be explained by placebo effect. No misfire codes, so I'm good. Ever notice how much smoother (happier?) your whole car feels after an oil change? Even the steering feels more like butter...
The "old" plugs (Denso FK20HBR11 (3473)) are shown below (D=driver, P=passenger, 1=front, 4=rear). Close up is of D1 on the left, P1 on the right. Negative electrodes (at bottom of plug) feel pretty rough; a buddy says that's because they run the engine so lean.
