What will you mostly use it for?
The DOIO is the more purpose-built choice for gaming with hitbox-style controls, and it is also the clear pick for switch changes. The O2 has the edge for everyday desk work and travel because it supports wireless connections and weighs less. For programming and content creation, the O2's connection options and described lighting controls are useful advantages, while the DOIO remains relevant if its specialized layout and OLED status display better fit your setup. Verify the O2's intended layout before purchasing, since its listing calls it a numpad while the vendor describes an 83-key keyboard.
