Well, my recall is that the PX wasn't an "upgrade," but a marketing retreat to the basic upward release heels used by all the other companies. It was meant to satisfy the average recreational skier who found the Pivot too tricky to step into or retain, especially in soft snow, and lacking the satisfying "click" of positive engagement. (Its "thunk" never seemed to excite.) I also think the Pivot may have had issues about forward pressure for racers, although the FKS was sure used for a long time without a lot of complaint, so not dead sure. The bit about lateral support seems to get argued both ways, I've seen plenty of ads that extoll the Pivots' 7 contact points and so on. PX's do not have the same flex range, it's a bit less, although still exemplary, and more to the point, they're completely different biomechanically. The location of the Pivot release upward is better aligned with the tibia, in terms of mechanical stress prior to release, and the pivot in the Pivot actually permitted some lateral twist at the heel complementing toe release. They're universally regarded as a slightly more leg-friendly heel (or seriously more leg friendly if you read some of the crazed KB threads), whatever you do or don't think about the sounds they make or the snow that gets in the pivot plate. Rossi Smash may not see much diff in leg safety, everyone's got their own take, but some pay attention to small advantages or disadvantages.
Phil doesn't like the PX because it's heavier than the Pivot, and because it has a significantly larger footprint, in terms of ski flex. He's on record about that. Seems like both parts are hard to dispute unless you have a scale or tape with a different outcome.
And I'd guess they're the best bang for the buck because they don't have as much demand for the existing supply, eg, Econ 101. That often signals a product that just doesn't stand out relative to its competitors. Sometimes "diehard" just means "they did it better the first time around..."
