Is it better to raise Su Mu or German shepherd?

I think it's better to raise Su Mu, so I raised Su Mu, my friend's German shepherd. I walk the dog with her every day, so I often communicate with her about raising a dog!

Su Mu: The Scottish Shepherd is a flexible, strong, active and lively breed. It is good-natured, easy to get close to, and full of energy when outdoors or outdoors. Rich feelings for the host, strong vigilance against strangers, and elegant and gorgeous appearance of the tower fascinate many people.

German shepherd: A good German shepherd gives the impression of being strong, agile, muscular, alert and energetic. German shepherd is strong, confident and nervous, never timid, and behaves meekly without stimulation. Be alert and tame. German shepherd dogs must be brave, tough and aggressive, and engage in all kinds of work all over the world. Breeders must pay close attention to German Shepherd, which is a very active animal both mentally and physically.

German shepherd eats more than three times as much as Su Mu. (The daily food intake of a friend's house, Demu = the food of the rice cooker)

PS: I think Su Mu is docile, while German shepherd is fierce!
