Default The best spark plugs for your van ?

Just checking out the recommended plugs for my 98 5.7 Express. Most people on here recommend AC Delco (which I currently have fitted) but I have an option of a budget 'Copper' plug thru to 'Iridium', 'Premium Iridium', 'Platinum' and 'Double Platinum'........
I use the van for commuting and do not do high miles. In 'Real World' terms is there a big enough difference in these plug choices to warrant the purchase of the more expesive plugs over the budget Copper ones ?
If the budget 'Copper' plug is fine when would you justify the expense of the 'Premium Iridium'plugs ? I suspect racing may justify it, but what do I know ????
