The first set might produce dogs that are more suited for high-level competition than as a family companion - this is where you talk, talk, talk to the breeder to find out what the goal of the breeding is, tell her exactly what your experience and expectations are, and decide if this breeding will produce a pup suitable to your needs.
The second pair would be an automatic no. No hip certs, no real breeding goals.
This is not a recommendation of the first breeder - I do not know the dogs, do not know what they produce, do not know the experience or goals of the breeder, do not know how they place puppies, etc. I would ask for a zillion references of as many people that have had pups from them, and contact their vet, and the local rescue and see what kind of feedback you can get.
In selecting a breeder, I would read through these articles to help you make an educated decision:
