I have not eaten a lot of different varieties of duck, but of those I have, Woodies & Redheads were my favorites. Never had the opportunity to try a Canvasback though I always heard they were fine eating.

Do not have much experience with geese either. I shot a young Blue once which ate mighty good. Only other geese I have eaten were Canadas. To my taste that Blue was far above the Canadians.
