The reason I like platinum plugs is because you can usually increase the change interval to 100-150K miles without any affect on performance or efficiency. I've ran several sets well beyond a 100K miles and only changed them then because I felt guilty not because the car was misfiring or getting poor mileage. Whichever plug you decide on be sure to use anti seize on the threads. The engine heat can cause them to seize in the aluminum head (been there done that). The set of platinum plugs I have in my '88 Escort probably has over 100K miles on them now and and still delivering 40-45 mpg with no misfiring.
