What will you mostly use it for?
The Agar Mini is the more straightforward pick for travel and office use, and its ready-to-use format also suits buyers who want to start working without assembling a kit. The Rhymestone has the edge for programming if a split ortholinear layout and OLED displays are priorities. For modding, the Rhymestone's kit format and optional LED and display-related parts offer a more hands-on route. Gaming and content creation lean toward the Agar Mini for its wireless setup and included keycaps, rather than any stated performance advantage.
Pick the PBTfans Agar Mini
- Bluetooth and wireless connectivity support a cable-free setup.
- The Agar Mini is described as ready to use and includes its battery.
