While that may be true, what is ultimately of importance is the power
delivered to the shaft of the motor. That is where HP and torque are
traditionally measured. What is better, a 15A motor with a 1.5 HP output
or
one with a 1 HP output. Efficiency and power factor must be considered.
Input power is meaningless if you want to know how much work it will do.

That's quite true. Why would a manufacturer want you to know the actual work
that their product will do? It sounds so much better to rig the numbers.

All the more reason to use the amp rating instead of the HP rating.
The amp rating is more strictly controlled.
