Resistive heat is 100% efficient, but heat pumps can operate at greater then 100% efficiency. That's because a heat pump doesn't actually generate heat, but just moves it around. Even when it's cold outside, there's still a lot of heat energy in the air, which can be moved inside to warm your home.

Due to the increased efficiency, heat pumps are better then electric resistive heat (when temperatures outside are within the heat pump's operating range, that is). This is regardless of the method of power generation.
