Yep, there's no way you can modulate the brakes faster than a computer w/ actuator. On pavement, ABS is the way to go. On extremely slick surfaces, such as snow and ice, ABS is still the way to go because a wheel slowing down still has more grip to the pavement than a sliding tire. On gravel, mud or sand, where a stopped tire will pile up the material infront of the tire, effectively "digging in," then non-ABS will help you stop the quickest, but may also get you stuck. All in all, if you have the option and don't mind the extra heft, ABS reigns.
