I was at the speed shop today. Speed Unlimited they are large mail order house just happens to be across the street from where I work. Anyhow the sales guy is usually pretty straight with me, and today he talked me out of buying the more expensive NGK Iridium plugs in favor of the Autolite Platinum AP-106. They were a hell of a lot cheaper than his NGKs and Accels. He claimed that for my mild buildup I would be just as well served with the standard platinum plug.
True? I figured I'd take his word - since he was down-selling, but he has done that on some other stuff like pushrods, which I had picked out some really expensive comp pushrods and he said I didn't need all that either.

Oh well - I like saving money as long as the parts do what I need them to do.

I wouldn't worry. IMO Autolite has made a top quality product for at least as long as my experience goes. And that's more decades than I care to disclose. I used a set of Autolite double plats in my stock blob sedan. After 70,000K miles, they still looked like new and the gap was still in spec.
I use standard Autolites in the Vette. That's because I like to keep them fresh anyway, so there's no use in buying plats for it since long life is their main benefit.

Reread the last part of the post by Notorious, quoted below. The ONLY benefit to the platinum plugs, is their longer life. There is no performance advantage. If you are a cruiser or waxer that pays to have his plugs changed, there could be an advantage to the higher priced platinums, with labor costs what they are. However, for most people I would expect to find in the tech area of a forum, tinkerers who wouldn't, couldn't, leave spark plugs alone for longer than the life of a standard plug, the standard plug will save significant money with no sacrifices. Your trusted sales person should have asked some more questions and continued his "down sell" even farther.
