I would be glad to read durability tests.
As in for example a Brown switch is how hard to press at first, and how it degrades.
Because I used Blue and Brown switches, and they both get mushy after a few years of use. Brown was like 1 year, Blue was ~2-3 before getting mushy. They both just lose that tactile bump feel to them.
The Brown cap kb was a Corsair Strife RGB, the Blue was a Razer BlackWidow. Cherry cap, original, older model.
Of course this test could only work with tactile ones as Reds don't change with time. For example Reds simply bottom out and that's the only feel you can get out of them.
