So, it seems you are saying that if something performs AS designed (regardless when it was designed), it's as good as it gets. I.e., it's all relative. When a 1936 tractor left the showroom floor, it cranked just as well at 0 degrees F as a 12 volt tractor does built in 1970.
If you truly believe that, then it's clear you never measured cranking speed revolutions on a cold tractor with either system. Many old tractors with good working 6 volt systems barely crank 75-150 RPM at 0 degees F. 12 volt systems typically crank 200-400 RPM. That can make a big difference with starting.
Using your reasoning, it has me wondering why on earth the 12 volt system became the norm in modern engineering?
