a power amplifier, like any amplifier, does not distort signals by much unless the max input is exceeded. If it is, the type of distortion depends on the design, but in general, it will clip the top and bottom of the waveform just like a limiter would.
A hard limiter, aka clipper, has a lot of distortion, as long as the input is large enough to put the circuit well into limiting.
The amount of distortion in either depends on the input waveform and on the amount it exceeds the max input allowed.
I would not classify either element as a nonlinear element. True, they have non-linear elements in them, but so does every other circuit in the world.
edit, re additional comments. No, as I said above, distortion depends on design and on signal inputs. On any it could vary from 0.01% to 50% or more. This is really a pretty silly question, why would you make that comparison?
