There was a considerable difference when I installed my new NGK plugs. My engine revved up easier and the fuel efficiency increased.

i put a heatrange colder (bosch FR6 because i can't get the ngk's local) in my bro's chipped 337 and it ran a lot smoother
Pros: ran a lot smoother
Vehicle:
Volkswagen Golf

good plugs, cheap, and I get zero misfires at 0.028\" gap on a chipped K03 Sport.
Pros: good plugs, cheap, zero misfires
They work beautifully. I've been using them for the past 24,000 miles. I change them every oil change (hey, they're cheap) and they seem to be the smoothest that i'v tried.
Pros: work beautifully, very smooth, cheap
Mileage: 38624 km
28R, NGKBKR7Es - 0.028" Change every 8K miles. Only $2.30 a piece, and I run lots of race fuel
Pros: cheap, runs race fuel
Cons: change every 8k miles
Mileage: 8000 km
i put in some 3922s and i can hear it misfire when its idling, but it seems fine when im giving it gas.
Pros: fine when accelerating
Cons: misfire at idle
Part number: 3922
I was running the junky ford plugs with little to no issues and switched to those NGKs and now I will actually foul a plug in warmup. This has never happened before and I would venture to say they are my least favorite plugs at this time. I have never had these issues until the NGKs.
Cons: foul a plug
i just changed my spark plugs, figuring i would do a tune-up before winter..the car was running fine before..changed the oem plugs that were in them to bosch +2's..well that was when the misfiring started...the car at low rpm's, lets say, 1500rpms, would stutter if i tried to full throttle it,...but when i get to about 2500rpms the stuttering would stop
Cons: misfiring, stuttering at low rpms
