Onyx Go Series
Score: 77/100
Gowenic Paperwhite eReader
Score: 71/100Rankings
The ONYX BOOX Go 6 delivers a crisp 300 ppi Carta Plus display and an 8-core processor with 2 GB RAM for smooth Android performance. Its lack of waterproofing and small 6-inch screen may limit extensive note-taking. Suited for users who need a powerful, ultra-portable ePaper device.

The Gowenic 5.76-inch ePaper tablet offers a 24-level adjustable front light and IPX8 waterproof protection, making it robust for reading anywhere. However, it lacks wireless charging and native stylus support, limiting annotation capabilities. Best suited for readers who prioritize durability and note-taking over premium charging features.

Products in the top-left offer the best value (high score, low price).
While no dedicated reviews of the Go 6 were found, analysts of the Go series emphasize its high-resolution 300 ppi screen, fluid Android 11 performance, and the versatility that Android apps bring, positioning it as a solid ultra-portable reader despite its modest hardware.
General consumer chatter praises the Go 6's portability, battery life, and ability to handle a wide range of ebook formats, but recurring remarks mention the limited RAM and small screen as constraints for heavy PDF work or note-taking.

Professional reviewers commend the Paperwhite 6.8 for its brighter, higher-contrast display, smoother navigation and modern USB-C port, but they criticize the lack of wireless charging and any stylus capability, noting that these omissions limit its appeal to power users who want annotation features.
Typical users love the waterproof design, long battery life and warm-light customization, yet many express disappointment over the gray screen when the light is off and the inability to take handwritten notes.
