Even if the efficicencies are relatively the same, sometimes a small bump in the resistance on the tweeter helps. I have a set that I built whose efficiences are the same on paper but I have 1.5Ohms of resistance in front of the tweeter.If you raise the resistance on the tweeter it changes the crossover's effective frequency to the tweeter. You need to account for attenuation and the tweeter's impedence at the crossover frequencey when you design your crossover.
More simply, if you add a resistor to a single 1st order crossover for the tweeter, you'll have to go to a smaller value capacitor to have the same effective crossover frequency as before.
The non-inductive metal oxide resistors have a better sound in my opinion too.
