No, they don't. At least not on dry pavement--there's no discernible

Actually ABS brakes do indeed work better on dry pavement. One might think
incorrectly that dry pavement would make all tires lock up at the same time
and there fore "fool" the ABS into thinking that the vehicle was stopped.
In real life the rear wheels will typically lock up first as the weight
shifts to the front of the vehicle and the rear tires then lock up while the
front tires are still spinning. And then there are instances when there is
an accumulation of sand or dirt on the street that causes a wheel or wheel
to lock up. Add to that list rough pavement that would cause a tire to
bounce off the ground during breaking and lock up. I have experienced all
three of those examples in my Tundra and the ABS brakes faithfully engaged.

But did you stop shorter than you would have without ABS and if so how
did you determine this? And why does every test comparing ABS with no
ABS on dry pavement conclude that it does not stop shorter?
