Traction control and ABS are very much aimed at mediocre all seasons from what I've found. No traction control in the Jeep, but with the ABS disabled and the Hakkas on it, the point of max deceleration rate on snow is well beyond the ABS activation point (and only a little before outright lockup).
Traction control sucks. The proof? My wife got a 2014 Impala last summer. 306ish Hp, FWD, traction and stability control, both able to be switched off. I had Firestone Winterforce snow tires on it. I wanted to see what the traction control was like, so I had her back out of the driveway and try to pull out. It would spin one, than the other, than the first again, and so on. The best thing was that it wouldn't move because the other side had the brake on to keep from spinning! I then had her turn off the traction control, and spin moderately up the hill. Away she went.

That sounds about right, with the Altimax Artics I find you take off best with a fairly hard launch by winter standards to really get them turning (and thus cleaned out) for the first few feet.
