What will you mostly use it for?
The EK21 is the more compelling fit for buyers who prioritize key customization, silent switches, or a lower carry weight. The AL21 makes the stronger case for a metal-bodied desk setup, especially where its aluminum knob and RGB controls are useful. Both provide hot-swap support and a knob, so those shared features do not decide the comparison. Buyers considering the AL21 should account for its south-facing lighting and the stated keycap caveat.
Pick the Epomaker EK21
- The EK21 lists a 1000 Hz polling rate, a specification not listed for the AL21.
- Its linear switches are described as silent, while the AL21 is listed with linear switches.
