You drive a lot of miles in many conditions I am sure. My point is that in light snow ABS will not stop faster than non-ABS if you know how to use conventional brakes. Light snow they will not lock up and thus will not allow the tire to get down to the pavement. I have ABS on my Tahoe and pull the fuse when I am in heavy snow. I prefer to have the option of steering or allowing the tire to bite down at low speeds. Often times you may want to get a little crossed up by using the brakes. Best of both would be ABS but have it sense when vehicle speed is low (say below 10mph) and brakes are applied but the vehicle is not slowing much. Under these conditions allow it turn it off and permit the tire to dig down to pavement.
Such a setup is not available so I, for now, will pull the fuse when I am plan on going slow in snow. 70mph on the highway ABS is nice. 10mph rolling towards an immovable object with ABS pinging away and not slowing much when you damn well know with 4 locked tires it would bite down to gravel or pavement, it blows big time. Try it when there is an inch or two of snow in a parking lot. Make two passes at 10 mph, one with ABS and the other without. Measure the distance that ABS increased your stopping distance and what speed the begin point of the delta would be. About one crunched hood, a few fenders and a front bumper.
Plan ahead and use common sense and you are better off without it when very slippery at slow speeds. You should not be going very fast in these conditions anyway. Rain or highway speeds when slippery it is a plus.
