For the Yanmar, much better dealer network, lower parts prices, and much easier to get parts. As far as reliability someone else besides me will have to answer that. But the Yanmars are virtually bullet proof. But the question that comes to mind is why. Electrical damage should have very little effect on the Volve, and a replacement and changeover would take some real serious bucks.
