I’m sure they are good (they don’t drift), but we’ve all grown up with “regular” joysticks and they were fine. Now all of a sudden, hall effects is the latest gaming buzzword that all gamers apparently need to get. Not saying that hall effects don’t have positives, but I do find it funny that all of a sudden its a big deal in the industry.
Hall effect has been the norm in all but the cheapest sim gear (sticks, throttles, etc) for a very long time now.
Hall effect gimbals on radio control/drone controllers have been pretty common for some time, too.
It’s mostly that this is a solved problem that more general purpose controllers are just now catching up to after the problem’s been exacerbated by the smaller gimbals used in modern controllers.
My understanding is that no first party controller (Sony, MS, Sega or Nintendo) uses hall effects.
