ABS and EBD
ABS and EBD control modules assist with only heavy or emergency braking. EBD only works when ESD is turned on. in the event that the ABS control module or sensors fail, you are still able to use the traditional hydraulic braking system. While it is convenient, it is not in complete control of your brakes (IE if the control module board fries you are left floating in a death trap). electronic boards have stricter conditions it needs to operate; temperature, shock, and humidity than hydraulic systems do. this is why they appear more reliable and in most cases are.
as for them being a pain in the arse, i completely agree. but as for them being more reliable and in control of braking in cars i disagree.
