Seriously, I prefer stuff I KNOW works over untried gimmicks and I have used platinum so I feel fine recommending them to others.
Never used Iridium yet, but if GM uses them, it's for a reason.
The main reason automakers are slowly making the switch to iridium is that is lasts like platinum, but doesn't retard ignition timing like platinum does. It allows a better spark, so you can run wider gaps, which acts as a timing advance in a way which increases MPG.
