Well most of the current runs along the surface of the wires so the more wires you have the more current can travel through the wire. This is not much of a factor in automotive use as long as you use AWG wire designed for vehicles.
The strength factor may come into play where movement can cause broken wires and loss of conductivity.I might use a larger strand in that case but I think I would just go with a larger gauge for less resistance than worry about broken strands. Case in point would be the alternator conversion to 100 amp or higher. Then go from 12 gauge to 10 or 8. JMO.
