Duck meat is generally considered to have a richer, more flavorful profile compared to chicken. It is higher in fat, which contributes to its dense and hearty texture. Duck meat is also higher in vitamins, particularly iron and copper, and has a slightly lower cholesterol and sodium content compared to chicken.
