For airheads, there isn't a big advantage (or any) for using exotic multi electrode plugs. The combustion chamber is designed for normal plugs. However, the iridium has to do with the electrode. It allows it to be smaller and last longer. In that regard, it shouldn't matter. The plugs will last longer, and spark well longer, but will cost more. So its a matter of choice.
