What will you mostly use it for?
The TH40 is the more straightforward fit for gaming, office use, travel, and content creation, largely because it is pre-built and has documented wireless connectivity and VIA features. Programming is a close call: the TH40 offers programmable layers, while the Rhymestone brings a split ortholinear format. For modding, the Rhymestone's kit components make it the more build-oriented choice. Buyers should decide first whether they want a ready-to-use board or a kit that requires completion.
Pick the Epomaker TH40
- The TH40 lists a 1000 Hz polling rate and N-Key Rollover.
- It offers wired and 2.4 GHz connections, while the Rhymestone listing does not specify a polling rate or wireless connectivity.
