Assuming 15K miles/year at 25MPG, you will buy 600 gallons of fuel/year. If the cost difference between 87 and 93 is $0.20/gal, then you will "save" only $120 or about $10/month
For those of you who live in an area where the difference is only $0.10/gal, then you will save a whopping $5/month or $60/year.
Most of you don't have the time/resources Big Jim has to work on his car. (Like a Ford shop that he runs, not a knock on Big Jim, just the facts.) So your best bet is to run the fuel that Ford/SVT recommends.

Who knows gasoline is the cheapest fluid to purchase at the Quicky Mart, in any grade
Your tag line touches on a very important point. The brand of gas may be every bit as critical as the octane rating. I only use name brand gas. Chevron is my usual but Unocal, Mobil, Texaco, and Shell are also used frequently. Non of the cheap stuff from Arco, Thrifty, UltraMar, or the like. It doesn't matter how high the octane is if it is contaminated or poorly blended. It only takes a small quantity of water or trash to do a lot of damage. In my mind a tank of Arco 91 octane is much worse than a tank of Chevron 87 octane.[/b]I agree, but only to a point. Since most brands don't have local refineries, much of the gasoline everyone buys is essentially "plain label" gasoline. What makes it Chevron, or Texaco or Brand X is the additives.
I would love to burn Chevron 100% of the time, but it is not sold in my market, so it's either Texaco, Shell, or QuikTrip in my market. And, I'm pretty sure most of those fuels come from the same two refineries in my local area. However, I suspect the add. packs are different.
One thing to also remember, is now that the EPA is mandating different fuel blends, there is a few dozen different fuel formulations that are in use around the good 'ole USA. So if brand X works well in Southern Cali, it is probably not the same blend in St. Louis.
But I do agree it is important to fuel at a station that appears to be well maintained, and does a high volume of business. This should minimize the possiblity that you get a bad tank of fuel, or more than your fair share of water in the tank you buy.
