The following is my understanding of duck meat and goose meat, which is now available to you:

Appearance:

Duck meat has many large pores and red and tender meat; Goose meat has fine pores, grayish white meat and delicate texture.

Taste:

Goose meat is low in fat, cooked properly and chewy and sweet; Duck meat is tender, earthy and lacks meat flavor.

Nutritional components:

Goose meat is high in protein and healthy in fat, rich in vitamin B 1, iron and zinc; Duck meat is also high in protein, but the overall nutrition is less than goose meat.
