Every tire is going to feel way better if inflated to a pressure which is on the "comfort" side of optimal pressure rather than inflated to maximum possible, that holds for good tires as well as Gatorskins.
With good tires, you simply get more speed and comfort at the same effort and tire pressure; the differences between a Gatorskin and a GP5000 are big enough to actually be able to measure them pretty easily with a decent hill, GPS and a powermeter, you don't need fun with maths to tease out the data. They kind of made sense for people who really needed the flat protection but now road tubeless works well, that'd be my first port of call if I had big issues with flats.
