Full-fat coconut milk is best. It is creamier and tastes better. Light coconut milk contains less fat and more water than regular coconut milk. The result is a thinner, creamier liquid with less coconut flavor. The homemade version is similar to canned light coconut milk. Full-fat cans have a richer flavor with a creamier taste. This is my favorite type to use in pasta recipes. But choose the type according to your personal preference.
