I would never use Gordon, but I have a slight soft spot for it because of the human character Gordon on Sesame Street.
I don't know any Gordons personally, and strangely, nearly all the real Gordons I know about and nearly all the ones in fiction are Canadian. Is Gordon a very popular name in Canada?
Don't like Gordy. It makes me think of someone who is like a gourd.
