Power is what matters.

Torque just explains the character of an engine. If someone says that an engine has a lot of torque, they usually mean that it has a lot of power at low rpm.

Low torque engines need high rpm to produce power, like motorcycle engines.

Power is the specification that tells you how fast a vehicle can accelerate, or how much load it can pull.
