Someone will understand a 100W or 200W amplifier, but
won't think of one having 3 dB more (power) gain than the
other.

That would be their loss. If you compare amp power in dBs, and remember that
it takes about 10 dB to create the perception of "twice as loud", then a lot
of things in the real world that may seem mysterious become understandable.

You got to consider that.
But, for understanding basics, knowing 6 dB is twice the voltage is what
people should know and use, and talk about. The only thing power
dB is good for is speaker dissapation and cost of amplifiers, and
indirectly, mains power. Forget volume levels.
