Alligator and crocodile meat don't differ too much in taste. They both have a chickenesque flavor and texture, though crocodile meat tends to taste a little fishier.
As far as nutrition goes, a 3.5-ounce serving of alligator meat provides roughly 46 grams of protein, 4 grams of fat (no saturated fat), and zero cholesterol. The same amount of crocodile meat nets you around 21.5 grams of protein, 2.9 grams of fat, and 65 milligrams of cholesterol.
