It's much better in most situations despite the "know it alls" claiming we'll all end up in a ditch. You'll still skid on ice with ABS, in fact you'll skid straight ahead just like you said. 4 wheel drive on the other hand guides you in the desired direction very nicely. Two years ago I watched about 50% of the vehicles (from semi's to Prius') slide right off the freeway while going under 5 mph. 4/all wheel drive vehicles made of the majority of those that remained on the road. I'll grant you that understeer is a real issue with 4 wheel drive. Simply lifting from the accelerator almost always corrects it.
Put it in 4WD, or WORSE, 4X4 (ABS/VS is disabled automatically) "apply" engine braking, the "weight" shifts frontward, you end up plowing/understeering into the car ahead.
