Hey-Hey!!!,
You'd have to specify the reason to use a resistor in order to say if choosing a choke might or might not be better. The choke is an energy storage device. If storing energy is useful, choosing a resistor over a choke is going to be hard.

Resistors are usually esy to put into the 'single parameter' category. If you're choosing a choke to present a load, you need to consider frequency response of the inductor. This frequency response is also not going to remain constant, as other parameters of the choke begin to surface. Capacitance being the primary paramter which causes chokes to behave like things other than inductances.

As Damir was pointing out, measuring these effects is not always simple.
cheers,
Douglas
