I wouldn't limit myself to those two options, in the last month or two there have been many fantastic releases in that size in and around the pricerange and also for considerably less.
Out of those two, I'd pick the Junglas. Thicker, stouter blade profile means more weight for throwing around chopping. Simple, efficient ergonomics, nice drop point for controlled tipwork and good belly for any slicing or chopping tasks. Buck is a great company and I have many of their knives, but I know with ESEE the F&F is going to be phenomenal.
Consider the Kershaw 1077 and the Kabar Heavy Duty series.
