just a which one would you choose question

beef is better but whichever is more quickly obtainable will do

they both restore the same amount of hunger and saturation. Pig our guaranteed to drop at least one piece of pork while a cow may drop none. However cows also drop leather with can be useful for armor. So it just depends whether you want more for or a little less and armor, though cows don't drop that much lower of a percentage of food than pigs it is something to take note of. Edit: As a food source though not taking into account drop rates they're 100% equal

Pork is just satisfying to eat for me I don't know why. :D
