I had a bike with ABS, rode it for three years and put around 21,000 miles on it. Only once for sure did the ABS kick in and it was because I wasn't paying attention to the road in front of me, when I turned my head back around the traffic had stopped and I hauled the bike down jamming on the brakes. The nose dove a little but the bike stopped straight and true. This was my first bike and my first season riding, glad I had the ABS that day. Don't know if I would have stopped the bike in time without it.
Every bike I've owned since then has been without ABS. For what it's worth, I haven't been down on any of my bikes either and hopefully won't. All things being equal I would prefer ABS on my bike but I wouldn't let it be the deciding factor.
