Kensington Expert Mouse Wireless Trackball vs Ploopy Thumb Trackball

The Kensington Expert Mouse Wireless Trackball and the Ploopy Thumb Trackball are both trackball mice, but they use different control styles. The Kensington is a finger-operated model, while the Ploopy is thumb-operated. Neither is inherently better, and the choice largely comes down to personal preference and any specific ergonomic issues you deal with. The Kensington is wireless and supports both a USB receiver and Bluetooth connection, while the Ploopy is wired-only. The Ploopy is also much bulkier and has a distinct DIY look and a rough 3D-printed finish, but it's also far more customizable on both a hardware and software level. It's available as a prebuilt unit or a "build-it-yourself" kit and supports VIA and QMK for customization. It also has a higher polling rate and a newer sensor, making it the better option for gaming.
