Mt goat isn't goat, IIRC - it is most closely related to antelopes. But somewhere up the line, they are hooked together. I think...
And as with most meats, it depends on the individual animal, what they have been eating, how killed, how taken care of, how prepared.
The yearling billy I killed years ago was top notch eating.
I've never knowingly eaten domestic goat, but I sure don't care for the cheese.
