Which cat or dog food is most tasty?

I read about people (mostly elderly) who have so little money that they eat cat or dog food. Watching the current pet food commercials, I wondered to whom they were appealing. The pet food is described as ‘balanced’ with vegetables (for basically meat eating pets) and delicious. The pet food companies advertise to sell product, but to whom? Pet owners or destitute people? Or both? Has anyone tasted pet food? If so, which is tastiest? For people.
