Well, that may be exactly the point -- when there are infinite options, that means those with $$$ to burn can outspend others to find the best, most exotic, pricey thing, and spend still more on test days and test them into perfection. One goal of spec classes, SPB in particular, is to define a cost-effective well-understood platform that is easy for everyday folks to obtain and build a competitive car upon. The PSS9's were extremely common and well-understood and easy to deal with during the formative SPB years, keeping in mind that SPB was defined at least a dozen years ago when the cars were still only about 10 years old.
Now, there is a monkey wrench thrown into this as of about 2 years ago: PSS9's were becoming scarce to the point of unobtainability, thanks to Bilstein no longer making them. Fortunately PCA worked with MCS to define a legal replacement shock that is close enough in performance to not require existing cars to switch over to remain competitive (though surely many have done so in the expectation that the MCS shocks are better); priced ... eh, roughly similarly; spares available individually; serviceable by the manufacturer; and with some contingency money possible (I forget the details on that). Better in every logistical way, but with the same performance so as not to obsolete the fleet of existing SPB cars.
So: if you're building now, definitely install the MCS shocks! (Check the latest rules -- you must have found a sheet that's not up to date if it says PSS9 is the only option. Current rules describe this in SPB section 4.E.

(On my SPB I still have the PSS9s that I bought used in 2005, and had rebuilt in 2017.)
