Will the factory sensor work, or is the Bosch aftermarket sensor recommended?

The factory sensor is of the second harmonic tuned type. I think subaru's from 2001 also uses this. What are the experiences with the stock sensor compared to the aftermarket?

I have found the factory sensor to actually be pretty good. Although it may be tuned to the second harmonic I've still generally have the best success with the ECU listening at the first.

I have only every had to move one car onto the second harmonic as it was picking up some strange noise on the first, i've also tried it on other cars before and not had success with it.
