The problem with those ABS/non-ABS comparison videos is that nobody brakes like that in real life. You can't treat a bike with no ABS in the same way.
Totally biased.
Expert riders cannot outperform ABS in the wet. There's a video about that.
Let me find that video and I'll back in a while.

Here it is, it is not in English but the only thing you need to know is that the orange one has ABS, the white one doesn't and both are professional, experienced riders.

[TITLE]Does ABS matter on a scooter?[/TITLE]
-Hi, do you know what is the difference between a scooter with ABS and one without when you brake up to the limit?
We are going to test it over a dry and wet road here, in the tracks at the INTA, "Instuto Nacional de Técnicas Aeroespaciales" (National Institute of Aerospacial Technics).
And we're going to try it on two scooters, Kymco Super Dim 305. One has ABS, the orange one and the white one does not.
For the tests, we have two professional riders with scooters that have stabilizer wheels which will avoid them to fall in case they lose control.
In the first test, over dry sliding asphalt, the riders will brake hard as soon as they speed up to 50km/h, we're going to make several tries with the riders switching scooters and we're going to measure the average stopping distance.
After several tries we found that the ABS equipped scooter stopped at 17 meters, the same distance as the white one which doesn't have ABS. There is no difference and both bikes came to a safe stop.
But, let's see what happens on a wet track.
It's clear the benefit of ABS on a wet road, on average the scooter with ABS came to a stop on an average distance of 22 meters and the one without on 29 meters but the important thing is that thanks to ABS the wheels don't lock, don't skid and it's harder to lose balance, even if you're a good rider, ABS can save you, at least, from a frightening experience.
