The resistor gives a good low frequency response, while the inductor gives a good high frequency response with worse matching. It is desirable to have the impedance of the pullup to be high, but if a resistor is used, then there could be too much DC drop. If an inductor is used, it is hard to find one good at low frequencies and around its self-resonant frequency. One approach to address this is to use a series resistor and inductor followed by resistive pad.
