Agreed. The best writing is based on taking into account the subject matter and the intended reading audience. The same is also the case with oratory skills.

For example; as a fan of detective fiction i just love the different language styles of Arthur Conan Doyle, Edgar Allan Poe, G.K.Chesterton, Agatha Christie, Dorothy Sayers, Rex Stout etc. Each is unique and designed for the character being depicted but all are enjoyable.
