tube Watts vs solid state Watts


Hi folks, can anyone explain to me why 20W tube amp is more powerful than a 20W solid state amp? Further: a 20W pure class A amp is more powerful than a 20W class B amp. Why is that? I've always thought Watt = Watt.

A watt is a watt, an amp is an amp, they all just amplify a signal, and probably sound alike. Or not........
