Logitech MX ERGO vs Kensington Orbit Wireless Trackball with Scroll Ring

The Logitech MX ERGO and the Kensington Orbit Wireless Trackball with Scroll Ring are both wireless trackball mice designed for office and productivity tasks, but the Logitech performs better overall. It has a right-handed ergonomic design with the trackball on the left side under the thumb rather than mounted in the middle. It has more programmable inputs, feels better built, and has significantly better click latency. On the other hand, the Kensington has an ambidextrous design, comes with a detachable wrist rest for extra ergonomic support, and uses a ring around the trackball rather than a typical mouse wheel for scrolling.
