Xbox Wireless Controller VS Sony DualSense Wireless Controller
Verdict DROP IT DROP IT
The Reality A class-action lawsuit filed in April 2020 by law firm Chimicles Schwartz Kriner & Donaldson-Smith alleged widespread 'stick drift' -- the thumbstick registering movement with no input from the player -- across Xbox controllers. An expert examination cited in the case attributed the defect to the controller's potentiometer, where a grease-like lubricant causes resistive material to scrape off a curved track and generate unwanted signal. The lawsuit alleged Microsoft knowingly distributed poorly designed controllers; in February 2021, Microsoft moved the case into arbitration rather than a jury trial, where it has continued outside public court proceedings. A class action filed in February 2021 by Chimicles Schwartz Kriner & Donaldson-Smith on behalf of PS5 owners alleges the DualSense suffers from a 'drift defect' that moves on-screen action without any player input on the joystick. The complaint alleges Sony was aware of the defect through online consumer complaints, direct customer complaints, and its own pre-release testing, but failed to fix it. According to the filing, subsequent software and firmware updates did little to resolve the issue, and customers with in-warranty controllers still had to ship them to a repair center at their own expense.
SHORT ANSWER
Xbox Wireless Controller: A 2020 class-action lawsuit alleges Xbox Wireless Controllers have a specific, named defect -- a potentiometer/lubricant issue -- that causes thumbstick 'drift,' and that Microsoft knew about it; the case moved into private arbitration in 2021 rather than a public trial.
Sony DualSense Wireless Controller: A 2021 class-action lawsuit alleges Sony's own pre-release testing found the DualSense's 'drift defect' before the controller launched, and that subsequent firmware updates failed to fix it, leaving owners to pay for their own warranty repair shipping.
