What will you mostly use it for?
The R75 is the more practical choice for everyday typing, office work, and gaming because it is a full 75% keyboard rather than a four-key pad. The DOIO makes more sense when small size and dedicated macro controls matter, including as a travel companion to another keyboard. For modding, both offer hot-swappable switches and QMK/VIA, with the DOIO adding a translucent acrylic base described for customization. Content-creation needs depend on whether the priority is a dedicated small control surface or a complete programmable keyboard with a knob.
