mx red and mx brown use the same force, they only need 45g to press down the key easily, means their spring are kinda light.good for touch typist. the only difference is cherry mx brown give you tactile feedback.
mx black need 60g force to press the key down, actuate after 2mm key travel. it's spring are harder. for some1 who have strong fingers. if you have soft finger want to touch type on mx black, is kinda hard. mx black are for those who prefer silent too, because they are linear, they not clicky, and they need higher force like 60g, the higher force will prevent you from bottoming up the key, and without bottoming up the key, you will reduce alot of noise.
And till now my favorite still linear non-clicky and using 7G, so looking forward for MX red. (Blue 1 just too noisy)

Anyway, it should be very durable, or should say it won't fade off forever ever after.
