Iridium tip spark plugs

Hi. can anyone guide me about the performance of Iridium tips spark plugs. Are they better then the conventional spark plugs. Are the other 2 and 4 tips spark plugs better then these.

they make absolutely no difference unless you have spark amplification (like MSD),... i've tried using Iridium plugs in my car (with a V6) and there wasn't even a 1hp difference felt.
