Well, whether it takes less energy would obviously depend on how the hoisting is done. But one advantage is that you can hoist slowly if that's advantageous, whereas you can't do things slowly with a rocket, at least until you've achieved orbit.
Also, if we start with a rocket+fuel on earth, and end with a rocket on the moon, there's an inevitable input of energy to move the rocket to a location of higher gravitational potential, that would have to be provided with hoisting as well, but there's also be a lot of rocket exhaust (formerly fuel) that's now zipping around the solar system, carrying away energy.
