What will you mostly use it for?
The Ducky has the edge for gaming on the strength of its stated polling rate, and its extra navigation keys make it a more direct fit for programming. Office use is a close call: the Ducky provides dedicated arrows, while the RK61 offers wireless connections. The RK61 is the travel and switch-swapping pick thanks to its stated weight and hot-swap design. For a desk setup that benefits from RGB and dedicated media controls, the Ducky is the more fitting choice.
