Uh.. Depends. I'd say Trac - if you're moving (too enthusiastically) in a dangerous zone, the traction control can (arguably) regain control (er.. traction) better/faster than you could by braking. LSD won't be able to do that.
Also, starting from a standstill on a ramp covered with snow is no feat easily achievable without traction (LSD won't do much good here).
LSD is mainly targeted at maximizing grip in corners.
Did BMW offer traction control on 5-spd 6 cyl e34's?
I have a '93 525iM with no traction ctrl, does that mean I got the LSD?
To my knowledge, there was no connection between them. I have them both but I understood that was a pretty rare combo.
To check whether you have LSD, jack up the rear axle, put the car in 3rd (?) and spin one of the (rear) wheels. If you have LSD, the other should spin in the opposite direction.
