Thanks for reminding me, I never remembered to take a look at the rubber while I had a microswitch controller open to see how it differed. Turns out it (Vader 3 Pro, left) uses solid stiff rubber cylinders that press down on the switches with little to no flex involved, compared to a typical membrane rubber (PS4, right) which completely collapses to contact the PCB. I always worried microswitches under rubber was simply adding an extra failure point, but this style seems far less subject to wear.
