I've pretty much only eaten animals that literally ever other person in this country has eaten (cow, pig, chicken, turkey, fish)... So I think my answer would be chicken. Steak I get a lot of pleasure out of, but I think that is due mostly to how its cooked. Other types of beef can be mediocre. Chicken can be made or broke depended on how its cooked too, but Chicken without much seasoning/sauce/breading still tends to taste really good while steak without much of the above tends to taste too plain.
