Okay, here is my take. It used to be it took cubes to make HP and torque because of the way an engine was aspirated and timed. Thermal efficiency (if I can remember my thermodynamics) is around 35%. With the advent of turbo, variable timing, direct injection and a host of other improvements, I am guessing they are getting the efficiency up around 50%, closer to that of the diesel cycle. If you do the same technology on the 5.0 or the larger engines, you should see a like rise in thermal efficiency and power output.
As far as problems, the Ford 5.4 had it's share. Plugs blew out of the block in the earlier ones, and in the later ones, you couldn't get them out without breaking them. After quite a few years of production they resolved these problems as well as a one piece spark plug. I don't think you hear a lot about plugs breaking because owners usually don't change them. When you do, it is quite problematic (and expensive if you take it to a dealer).
Each engine series has it's shakedown problems. Changes are expensive until a problem is identified as a real problem, not just an isolated oops. Recalls and TSB's are very expensive, so they need to get them right.
Sorry for rambling.
