Score: 69/100
Kobo Libra Colour
Score: 76/100Rankings

The Kobo Libra Colour is a 7-inch colour E-Ink e-reader with a larger screen, 32 GB storage, physical page-turn buttons, and optional stylus support. Battery life is shorter than monochrome rivals and storage cannot be expanded. It appeals to manga enthusiasts and note-takers who want colour and a bigger display.

The PocketBook Basic Lux 4 is an entry-level 6-inch e-reader with a crisp 212 PPI frontlit display and excellent battery endurance. Trade-offs include a fixed frontlight, limited Wi-Fi band, and lack of Bluetooth. Ideal for budget-conscious readers who value portability and broad format support.
