This is all extremely non-technical, guys. The F-16 is a more efficient turning machine than the Hornet as a result of its relaxed static stability. The Hornet sacrifices some of that sustained performance for great low-speed performance. Aircraft design is trade-offs.
I don't want to fall down the rabbit hole with you guys, especially not if we're going to make up stuff about "lossy" flow. (No offense. :D) Suffice to say, I look at the F-35 and see some very interesting design choices. I don't think we can easily predict its performance by comparing thrust to weight ratios and wing loading. Aircraft design has changed significantly, and a close look at the design and shape of the wing and the blended intake chines reveals some of their complexity. Things have changed, and many of the F-35's vocal naysayers like Pierre Sprey and the dunces at Airpower Australia have an outdated mode of thinking. Sprey himself predicted the F-15 would out-turn the F-22, with a similar analysis based heavily on thrust to weight ratio and wing loading. Boy was he wrong.
As a pilot, I look at this thing not without a bit of suspended awe. Perhaps based mostly in the mystery of the unknown, but I think there is more to this thing than meets the eye, and we've seen very little.
