I have had no problems using the NGK BKR5EKU plugs. I do not spend the extra money for the platinum version. The copper plugs are fine.
Pros: no problems using
Part number: BKR5EKU
Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.
Pros: smooth car runs
Cons: no misfire code
Vehicle:
Volkswagen
On a stock or chipped VR, the NGK platinum OEM plugs (BKR5EKUP) are pretty good. I have tried the Bosch F6DTC (16V copper plugs) and NGK R5671A-7 (copper) for about 10K and 6K miles respectively on my supercharged VR and both seem equally good.
Pros: equally good
Mileage: 10000 km
Part number: BKR5EKUP
I know LOTS of people running NGK BKR7E's who are chipped w/o problems.
Pros: no problems
I've had much success with BERU plugs on all of my VW's, especially my 16V's. Beru maks the stock/replacement plugs for Porsche, VW and Audi (I work at a Porsche dealership, I see it all the time)
Pros: success with BERU plugs

i had a buddy purchase me a set of bosch platinum plugs. i installed the plugs this morning before going to work, removing the old plugs, i found the number 1 and number 2 are wet with fuel. after installing the platinum plugs, i cranked the engine. and it started! the idle was smooth. i took my vw to work today, and the engine pulled smoothly in all rpms!
Pros: smooth idle, engine pulled smoothly
Cons: old plugs wet with fuel

I have autolites, they work well, but the car became jerky at part throttle when gapped at .024, runs better when opened wider for some reason.
Pros: work well
Cons: car became jerky
don't feel like changing them every oil change like I did with the autolites that constantly misfired...
Cons: constantly misfired, frequent changes
Platinum +4s are the worst plugs you can use. They have a bad habit of losing tips into the cylinders. I don't think I need to explain the results of that.
Cons: lose tips into cylinders, worst plugs
