I think that the quality of the robotic appendage is at the root of this question. I mean, is it high-tech robotic, almost like bionic? Or is it sort of janky and you're always having to fuss with it? If it's a good quality robot, then I will go with leg. I think it would be easier to get used to walking with a robotic leg than it would be to learn how to use a robotic hand. And like Jen said, if it's my dominant hand, then leg for sure.
