I have only owned one GSD, "Panzer", and he was LH. His coat wasn't a good example of LH, I don't think, as it seemed to be a bit curly over his rump area. As for the personality, well, Panzer was a real teddy-bear! He didn't have a mean bone in his body. He let our Boxer bitch steal bones from under him (not the chooks, tho'!) and when our cats were tiny kittens, he developed a bond with the male and would let the little fellow put his head in his mouth. When I came home with a baby (Heidi), he had never had anything to do with babies. My midwife loved Panzer, and sat down on the step next to him and "showed" him the new baby, explaining to him what it was all about. Whenever Heidi cried, Panzer would run in to check that she was OK and would come to me or David and "tell" us! He even broke the "no dogs on the carpet" rule in doing so! The downer for me with LH, was the clumps of fur around the house, which is why I chose a Boxer for our next dog.
