It is not safe to assume the ability to drive a headphone through just impedance. There are just too many variables, like sensitivity, efficiency of the drivers, varying frequency and the likes. Some low impedance headphone could just be as hard to drive as a high impedance headphone.
However, given a choice and a well-powered amp, high impedance loads are more preferable. You get maximum power transfer between your amplifying circuit and load while minimizing the transmission losses that occur in between.
