You are describing a GSD and those things you heard are generalizations that are often poor descriptions. There are more than two lines of GSDs that you will come across. Originally the breed was supposed to be a working dog that had to have it's working ability and structure approved by a Koermeister before it could breed. Some working lines and West German Show lines still abide by this standard. You will also find American show lines, Shiloh shepherds produced by out crosses and people that breed dogs way outside the standards and call them King shepherds or Old or Original shepherds. The quality of any line depends on the ability and diligence of the individual breeder. This forum is helpful for a variety of things but it gives a tiny representation of quality breeders, you will do yourself a disservice if you use this forum as your only means of searching for a breeder.
