Kensington Orbit Fusion Wireless Trackball vs GameBall Mouse

The GameBall Mouse and the Kensington Orbit Fusion Wireless Trackball are both trackball mice, but they're for different uses. The GameBall is better suited to gaming thanks to its higher polling rate, which produces smoother-feeling cursor movements, especially if you're using a higher-resolution display. Unfortunately, it has high click latency, making it unsuitable for competitive gaming.  It also has an ambidextrous design, while the Kensington has a right-handed shape. Conversely, the Kensington is better suited for office and productivity tasks. It has more precise-feeling scrolling features thanks to its scroll ring, and it has a thumb and pinky rest for extra support. It's also wireless-only and has companion software.
