Is an induction motor a good thing for small appliances?

Hi, I am researching a food processor (kitchenaid). It has 700 watts,
1 HP, and an induction motor.

I have heard/read that watts and HP mean little as this does not
express the efficiency of the motor. I have no idea if that is true or
not.

Then I read the food processor has an induction motor. I have been
reading about various induction motors on wikipedia and other places.

I am trying to find out why an induction motor in this food processor
is a good thing or if it matters if it is an induction motor.

Thank you for any help.
