That means lighter bottoming force being good in case of having some crouching/running key to keep pressed.
Also that key is usually pressed with pinkie, which is the weakest and most easily stressed finger to start with without having any medical condition.
From Cherry MX switches Brown and Red are good for that.
Red has linear force curve, but that just means it doesn't have much any resistance before actuation point.
So if you have only used membrane/rubber dome switches, it could easily cause accidental presses...
Unless paying attention to keeping fingers lifted, which could also cause some stress.
Brown has nonlinear force curve with some resistance before registering key press.
Hence resting fingers on keys doesn't cause as easily accidental presses.
Omron made Romer-G used by Logitech is quite similar to MX Brown with little faster actuation and less travel distance and would be quieter if you don't like noise.
With light coming from center of switch those have very even illumination of cap markings:

(Creative's Vanguard K08 also uses Romer-G or its slight variation)
If paying any more than basic price from keyboard I would suggest also looking that it has dedicated multimedia keys/volume control.
Any second function jerry rigs just aren't really functional and are PR BS features.
While having that direct volume control makes it actually usable.
Logitech G810 has now extremely good pricing for its features with full RGB lightning and dedicated multimedia keys
Quite a lot of even expensive keyboards lack dedicated volume control.

G910 with extra macro keys and fancy look is still at very good price but out of stock:

If I had such pricing here in Finland might order immediately.
Something little quieter than current (120€ priced at time) Logitech G710+ would be nice. (MX Brown with factory installed noise dampening o-rings)
With standard non transparent casing Cherry MX having LED at one side of switch it has also some cap marking illumination issues in caps with more markings.
