I don't believe one is any more or less reliable or easy to diagnose than the other. Keeping terminals and connections clean should result in the two methods performing essentially equally. The only difference I've observed over the years is that in a poorly maintained condition, positive-ground systems tend to generate their electrical corrosion at the ground/engine block connection, and negative-ground systems tend to get theirs at the battery terminal.
