Push-pull output is most popular output stage for op-amps and audio power
amplifiers.

** Too many errors and misleading claims to even know where to start.

Push pull output stages can operate in class A, B or AB - the latter being
by far the most common.

Each output device amplifies an input signal of one polarity ONLY if the
load is resistive.

The efficiency of an ideal class B output stage varies from zero to 78.5% at
full power.

The efficiency of an ideal class A output stage varies from zero to 50% at
full power.

So both are horribly inefficient at low power.
