I agree with the earlier statement that it really depends upon the dogs in the pedigree and how they manifest, not necessarily the lines. So I don't know how useful the generalizations are.
That said I have a four year old female from east german lines and a young male (~1 year old) from primarily west german working lines. Love 'em both, but they are very different dogs. Generally, the wgwl male is higher drive, carries more aggression, has a more protective nature, and has higher thresholds.
There are two differences that come to mind that really stand out. First is structure: the "DDR" female is built like a tank. In football terms, she is built more like a middle linebacker whereas, in comparison, the male is built more like a wide receiver. The male carries just as much bone (if not more) in the leg and has a nice head, but the DDR female is significantly broader across the back and has more of that DDR head. The male will fill in some, but the female will always be broader - just a different body type. Although the female is right up at the top of breed standard, given her body proportions she appears compact (particularly when standing next to the taller and longer wgwl male). She is also very agile.
Second, biddability and interactiveness: Get the DDR female out of the house and she is primarily all about what she wants and often has her own agenda. If you have what she wants, you have the keys to the kingdom. However, if she wants something else more, she'll do what she wants and beg your forgiveness later. Biddability is not her strong suit. If I could carry around live rabbits I would be golden!
In contrast, the male wgwl lives to interact with you, always is trying to read your mind and anticipate what you want, and is quite biddable. Even in a high state of drive his ears are always open and he is responsive. He is also very motivated by praise.
Like I said before, I do not know that these differences can be generalized to the lines, but those are some of my observations.
