When configured in typical amplifier topologies, THD is vanishingly small at

That may be true, but only because of the negative feedback that Trevor
referred to. The basic device IS more nonlinear.

But when given suitable NFB, the transfer characteristic IS 'cleaner'. Very little
odd harmonic distortion (the nasty stuff) and very very low crossover distortion
(which makes a big difference).

I know, I've designed audio amps with both types. As in designed from the ground
up for commercial pro-audio sale.
