I'd go for whichever one is cheaper. You can go on www.wikipedia.com and look up the differences between platinum and iridium.

PS. What's your setup? If it's anywhere near stock, special plugs won't really do anything. I switched to Bosch Platinum 4+ and didn't notice a thing.

Colder plugs help prevent detonation in boosted, nitrous or high compression motors. Basically stock or hotter plugs hold more heat and therefore can cause detonation in certain instances.
