There was a very good article in TWO magazine a couple of years ago, James Whitham on a Triumph with ABS, and a Triumph without. In the dry, he could stop it very slightly faster without ABS. In the wet, the ABS was better, and by a bigger margin. I don't care how much of a riding god you are, James Whitham is better than you are. And of course, that test itself was biased because they were perfectly planned stops.
The best obs in the world can't completely remove the risk that some day you have to stop unexpectedly. Last time I locked the front was because a policeman stepped into the road from behind his van and put his hand up, stop, as I was riding past it. I saved the slide, though I'll freely admit that if I had to do it 3 times in a row I'd probably have crashed at least once, but I still hit the stupid ****. There's no planning for total idiocy.
The last time I actually lost the front completely was 100% my fault, I was tired and distracted by a car driving unpredictably further away and failed to notice a closer hazard. Well, it was the other driver's fault I suppose but I should have seen it earlier and avoided it. This is the one that I always think of, because I do have generally good bike control and forward obs but sometimes, you can slip up, or get distracted, or just simply take your mind off the job for a moment and that's all it takes. No rider is perfect. At the end of a 1000 mile weekend or at the start of a 2 mile 7am commute, mistakes can happen.
So yeah, I'd personally have ABS like a shot, on the front at least. And I own neither a BMW or a Honda
