Electrical vs. Mechanical Gauges

I really don't believe there are any plus or minus to either one. I think it depends on what you are trying to achieve, room, conditions. I've had both and the mechanical would seem like it would take a beating much easier than electrical. Let's say a dune buggy or mud bog truck. Water and electricity don't go well together. A mechanical temperature gauge has a copper wire that connects to the manifold with a fitting. It shows temperature with the ignition off or on while electrical you have to turn on the switch. The copper wire wrapped in a stainless coil is always shoved up under the dash but can be tucked out of sight. Same with the mechanical oil pressure gauge with a copper tube,,,electrical uses a wire of course. The mechanical speedo has a cable and the electrical has a speed sensor again,,, wires. Volts are basically the same in both forms. You probably knew 98% but maybe I shed some light on your question.
