Joysticks: Probably Still Drifty
Joy-Con joysticks use a potentiometer to read the voltage at a wiper that slides across a strip of resistive material. That material wears down over time, or plastic and dust can dirty the sensors.
Stick drift is a huge problem with other Switch models. One survey found that 40% of Switch owners had problems with their Joy-Cons drifting, and things didn’t get any better with the Lite or OLED editions. After a bunch of lawsuits, Nintendo’s president even admitted it and apologized, setting up a free repair program for customers in some parts of the world.
I’ve never had stick drift with PlayStation or Xboxes despite people telling me it’s a problem. The switch though is awful for it.
I don’t know what they do to make their analogue sticks so bad but they’re definitely getting them from the world’s cheapest supplier, apparently one that even Sony and Microsoft turned up their noses to.
PS/Xbox controllers have more internal space, so their joystick modules are much, much larger than what goes in the joycon. That means they can have more material in the potentiometers, meaning less susceptible to wear and dust/dirt intrusions.

JoyCon 1s also have a flap that dust can get into, and that’s likely a large part of the problem. This is fixed with JoyCon 2s, so I’m not sure why everyone’s jumping to the assumption that they will be equally brittle.
