Personally, I pick an oil based on the start-up and operational viscosity more than the additive pack. I think it's a bit of a fool's errand trying to outguess manufacturers when it comes to what additives work "best".
While I realize that single UOA's tell at best an incomplete picture of engine wear, there are literally hundreds of UOA's on here which demonstrate that any recommended oil changed at a reasonable interval will protect your engine adequately. But I haven't seen any data, or even trends, to suggest that one oil's additive pack is really superior to the other.
So, I really don't think there's a 'holy grail' of additives. The organic moly compounds used in large quantities by a few oils seem to have a lower COFriction, which will (marginally) help fuel economy, but I doubt there will be a quantifiable difference in wear.
I'm generally not one to just blindly trust companies, but the oils have to meet certain standards for wear protection, and all approved modern name-brand oils seem to meet those standards, regardless of the additives used. And I think the chemists in the additive business are more equipped to make those determinations than I am.
