Do premium spark plugs make any difference?

In the past, when I've gotten spark plug replacements, I've just gone with the standard Bosch, single arm plugs. By single arm, I mean the metal overhang that actually allows the spark to arc to it and ignite the fuel. I've seen plugs that have 2 and 4 arms arranged symmetrically around the end of the plug, I guess in order to provide a larger and more effective spark, thereby helping to ignite the fuel faster and more completely. Does anyone have any experience with these plugs? Are they all hype or do they really make a difference?
