What Are the Diffirences between Ballsrew CNC & Trapezoidal Screw CNC?

The ball srew and trapezoidal screw picture:

Ball Srew CNC: higher precision,higher efficiency, longer use of life, and a little noisy.

Ball srew mini cnc router such as CNC 3040Z, CNC 6040Z-S80, HY-3040 and so on are recomended.

Trapezoidal screw mini CNC machine such as CNC 3040T-DJ, CNC 3020 series, they are less precise and efficient as ball srew cnc, and also low noise.
