ELI5: Would a right handed person with a bionic right hand still feel more comfortable with that hand?
gpt
Handedness is more about the way your brain is wired, than about the qualities of your limbs themselves.  So a right handed person would most likely still feel more comfortable using their right hand. 

A common theory is that handedness is related to where your brain does most of its fine motor control. For most people, the left hemisphere does controls speech which requires fine control. The left hemisphere also looks after your right limbs, and therefore for most people, the right limbs are more comfortable to control.

tl;dr its all in your head - your left hemisphere is usually better at fine motor controls.
