Best for

What will you mostly use it for?

The GMK21 is a stronger fit when the priority is RGB, a physical knob, or QMK support. The TofuPad has the edge for wireless flexibility and its listed Mac/Win support and sound dampening. Modding is a split: the GMK21 offers QMK and 5-pin sockets, while the TofuPad lists several plate materials and VIAL support. Both are numpads with hot-swappable sockets and VIA support, so those shared features do not decide the comparison.

For gaming

Pick the Zuoya GMK21 Numpad

  • The GMK21 has multicolor backlighting, while the TofuPad lists no RGB.
  • The GMK21 includes a knob and 20 keys, offering additional controls on the numpad.
