Kensington SlimBlade Trackball vs GameBall Mouse

The GameBall Mouse and the Kensington SlimBlade Trackball are both trackball mice, but they're for different uses. The GameBall is designed for gaming use. It has a  higher polling rate producing smoother-feeling cursor movements, especially on higher-resolution displays. It also has an RGB lighting zone. Unfortunately, it has high click latency, making it unsuitable for competitive gaming. The SlimBlade is better suited for office or productivity tasks, so its scrolling feature feels more precise, though it doesn't have a horizontal scrolling ability. While both mice are ambidextrous, the GameBall has a palm rest in the middle for better ergonomic support.
