If you don't want xDrive then I would go with xLine personally. I wanted sparkling bronze and dark fineline wood trim but had to go with mineral grey and light fineline wood with M Sport.
We like the hydraulic steering. Feels just like my wife's 128i but a little heavier than my E90. Servotronic lightens this. I had planned to get servotronic but my wife said she didn't need it after test driving.
I have read reports that the servotronic option actually stiffens up the steering a little on the sDrive but have not verified.
