[Lowfer] Class E vs. Class C what's your opinion ?

   I have heard it argued  that a low pass filter (which is designed around a 50 ohm resistive load)  will not perform 
well into an electrically small, highly loaded antenna which will show a highly reactive load at harmonics.

   I have also heard it said that a highly efficient Class-E amplifier won't have much harmonic energy .(However even 1% is a LOT of harmonic energy to be radiating!)

   I don't necessarily believe in either argument but how do you refute that?
