I have the servotronic steering on my 03 4.6is and love it, but drive normal/conventional steering 3.0i and 4.41 X5s daily at work. My suggestion to you would be to drive both and make your personal decision from there. You can find an X5 with either, so if the steering feel of servotronic isn't to your liking you can find another CPO without it. (unless you are really wanting the 4.6/4.8is models

)
