Pekin's were bred for meat and egg production, that is what I would go with. There also one of the bigger breeds, Jumbo Pekin's, so that is helpful for meat.
What purposes do you want them for? Assuming egg laying and meat? Or meat, pets, eggs, breeding/selling, etc.?
Pekin ducks are great for dual purpose. They are large and great for meat, and lay 200-300 large eggs a year. They also make good pets, and are very sweet.
