I agree, I have the Penn 750 which is the smaller sibling of the 850 and its a great reel. In fact considering the Penn 70 had a cult status stretching several decades, which these reels have replaced, they had to be not just as good but better ! They are big time, wide spool, lovely action and line lay, quality and aftercare that other companys strive to achieve.
Had the Diawas for years but with the new range from Penn on introductory offer of £50 its no contest in my book with choice.
