I use Kurzweil not Open Book, but I can say that usually fine reader gives the best results. It sometimes creates more junk characters instead of skipping pictures, but within the text it seems just a tad better usually. Fine reader recognizes em-dashes correctly does not usually cause spaces in the middle of words, and seems a little better at guessing where blank lines should be in the text. Of course there probably are books that will work better with the other scanning engines, but if you don't want to mess around testing and your results are fine with fine engine, then I wouldn't try switching.
