What's the difference between a camera stabilizer and a one-shoulder racket?

Different ways of use, different stability, etc.

Different ways of use: Camera stabilizer is a technology that uses a tripod or stabilizer to fix the camera and shoot by manually operating the camera. Shoulder follow-up is a kind of camera installed on the shoulder, and the camera can follow steadily with the movement of the shoulder.

Different stability: the camera stabilizer uses a tripod or stabilizer to fix the camera, which can provide better stability and reduce jitter and shaking. Side-by-side following relies on the photographer's shoulder movement to achieve camera stability, which is relatively poor.
