Most dogs are just like people, they have individual personalities. There are general differences between sexes, and fixing your pet will alter their attitudes a lot. A neutered male is generally more happy go lucky, and more eager to please. A female can tend to get more reserved with age. I'm not saying that females are not playful, happy pets, but, they do seem to have a bit more dignity about them then the male dog that is turning circles and doing flips for your attention. :)
Above all, the best pet is a spayed or neutered pet. Most fights between dogs will happen between unaltered females, as in the dog pack make up, the females are incharge of the pecking order!
My best advice is to choose your puppy based on it's individual personality and how best it fits in with your family, and then get the puppy spayed or neutered at the appropriate time!
