Lida, had to think about this for a while then come back to give you my best answer.
I must also temper my answer because we have always had a multi dog household and think if it is a single dog family then it may be different.
In our family the females (all breeds) are a bit more independent and at times somewhat bitchy but loving and full of fun. My boys have bonded very close to us, are more needy but work so very hard to please, more showy in the ring but want us in their sight, where as my girls would probably go home with anyone who would spoil them. Both seem to learn the same, both sexes grow to be the best of dogs. I am starting to believe sex doesn't really matter as much as the breeding, whether from high energy lines or more calm.
This is our first time to have a female golden, and she is beautiful, high strung, learns so fast, but pushes the boundries. I love seeing what I can teach her next, but she needs watching and usually into something she shouldn't. I am having a blast with her! Male is more like our old golden, calm, likes laying around and sticks right with you on walks. He is a gentle, snuggle bug, was never mouthy, learns slower but retains learned things more completely. He is our class star and my baby for sure. Male has an off switch, Female doesn't. They are both following their parents in personality. Coop from pet, Kye from field/showing lines.
Our first golden was a smaller deep red-head, he was always on the move, always with us, would naturally hunt and retrieve. Our second golden boy was huge, a couch dog for sure, loved riding in the truck vs running and was our daughters best friend. Each males, but totally 180 degrees different.
I think it would be more what lines would fit into your lifestyle.. ie Conformation or Therapy/Pet, or whether the more higher energy..ie Agility/Hunting/Field and sex of the dog would be secondary. Both sexes make excellent pets.
