I have, they are nice for gaming. If you like typing on linear mechanical switches (eg. Cherry red), you may enjoy certain hall effect switches.
My experience with HE are on Gateron Jade Pro switches. They are light and very smooth with quick activation.
Interesting, I don't like reds normally. I prefer a heavy activation force switch so maybe I won't like all effect?
A lot of HE keyboards allow you to set the activation distance. Want more travel? Set it. Want to activate a single key press at one height, but repeat at another? Doable.
HE switches allow you to have a more programmatic keyboard. There is less to break. If the PCB has conformal coating, it is effectively waterproof (barring usb port).
The switches, like the Lekkers, can have the springs swapped out (like any other switch) to the kind of feel you prefer.
They last forever. The jades and lekkers that I know of GIVE UP on testing after 100M clicks (vs a standard of 50M for the high-end mechanical).
They could even have a click spring to simulate the feel (it just does nothing), tho I am not aware of any that do.
The real question is why aren’t ALL keyboards HE? Literally no downsides.
