I have to go with pig because of bacon and pulled pork. Porkchops are too lean these days and often tough unless I cook them on the smoker. On the other hand, smoked brisket is really good and sometimes I make pastrami which is really good, so it's a close to a tie as to which is better. My wife makes a steak Diane which is fantastic and I'm very conflicted as to which is really better, pork or beef. Now veal is also beef and there's veal marsala and scallopini and when the veal is tender both are excellent, so it might just come down to the last one I ate as to which is best.
