Controllers for Mario Kart World: What Works, Tested
Platform:Switch 2 (NS2)
Mario Kart World is the Switch 2 party game. If you want an extra controller for friends or motion steering, the controller needs a gyro. These are the controllers and adapter I've actually raced with on Switch 2.

TPAX Wireless Controller
Built-in gyro, so tilting steers through corners, and HOME wakes the Switch 2. Under NT$1,000 (≈ US$30), ideal as a second controller for friends. No amiibo support.

Do third-party controllers support motion steering in Mario Kart World?
Only if they have a gyro. I tested the TPAX Wireless Controller and the X One SE2 (with an Xbox controller), and both handle motion steering.
Cheapest extra controller for friends?
The TPAX Wireless Controller, NT$850 (≈ US$26) on sale, with Hall-effect sticks, a gyro and HOME wake. The cheapest of the ones I tested.
