Platinum v.s. Iridium

Greetings all! I’m looking for opinions once more.

Practically since they came out I’ve been running Bosch’s Platinum Plus plugs in all the cars I change plugs on, including my own of course. NOT THE MULTI ELECTRODE plugs, the SINGLE electrode plug. I’ve been very happy with these plugs.

But now I’ve got to change plugs again and I’m considering a different brand of plug. NGK makes a plug called Iridium IX. They look more appealing than the Platinum plugs. I know that Iridium is a stronger metal but I’m not so sure if it’s better at conducting and whether the plug will produce a better spark.

Which plug is the better? The Bosch Platinum Plus single electrode or the NGK Iridium IX?

I know that sparkers are sparkers and brand and metal will not make a great difference. But when you’re paying three dollars and a quarter for a gallon of unleaded plus, even a small increase in mileage is worth what it takes.

So anyone with an opinion, a testimony, some specs or test results, a drunken rant maybe? Please, toss it in!
