Different shaft weights and profiles, marketed in 5gm increments is a VERY different discussion than swingweighting iron clubheads. Shaft EI profiles are a can of different worms, so, I'm going to table that discussion.
From a physics perspective, it makes most sense to put the mass of the iron clubhead directly behind where the ball should be struck. PXG 'fine tuning' screws are closer to the top line, and away from the mass of the iron. Not all that different than PING i200s, or any PING I Series over the last several years. It's just a different way to perimeter weight your irons.
I suppose an argument could be made for PXG's special insert formula being a differentiator, but P790s, TMBs, and i500s do basically the same thing.
Again, I'm not saying PXGs are crap clubs. They aren't. They're just not all that different from the rest of the bunch.
Try to think about PXG in the same context of Club Champion. Club Champion offers a white glove fitting service, they can spine/flow your shafts, and they can swingweight your irons exactly to your specs, all in-house. It's a great experience. But, you can pay for your fitting and specs, and have an OEM build your irons for 1/3 of the cost. At the end of the day, they'll perform the same.
