About 50 pages left of the book now, and have been re-watching Wuthering Heights '09 ... and formed a new opinion. WH'78, frightfully dull as it was, must be the one version closest to the book. Well, except that the book fails to be be dull. The book is rather engaging and not as tedious to read as, oh, Jane Eyre . Emily is more to-the-point than her sister, doesn't go off rambling in purple-tinted prose about stuff that doesn't have an impact on the story or characters. She also doesn't show off her French skills time and time again, although instead, she writes in dialect, which is only marginally easier to understand than the French. WH'98, what I remember of it, is also at least semi-true to the book, but not quite to the same extent.
