I cannot comment on Sun-Tzu but the Jolles translation is quite good. I've read the Howard and Paret several times and this one excels in most places. In a few places I think the H&P translation with Princeton gets the sense of Clausewitz better, most of the serious scholars of Clausewitz recommend O. J. Matthijs Jolles' translation from World War II for its accuracy. I wish Modern Library had a hard back version available, or an option to get just Sun-Tzu and Clausewitz as standalone paperbacks because the thickness of this edition is cumbersome. After one only read, there are cracks in the binding and I do think this one will last very long.
