If you liked a Golden get a Golden. It would not be my own choice but I'm an elderly single male and any dog of mine would no more than see children from a distance.
What do you want your next dog to do better or different?
After that I'd buy the breeder or the line if given any access to the sire and dam. I think there can be as much difference within a given breed as across breeds.
I find myself objecting to the wording of "fully" trained pup. My own experience has been that a really smart started pup that continues professional training working with the owner and family under supervision while being a part of the family at home is more fun - that is no animal is ever fully trained and turned over and stays quite fully trained - either gets better or goes down hill.
