As I understand it, the motivation for switching to water cooling isn't so much because it's "better" per se. The "modern" turbos are variable geometry, which means they have an electronic acuator attached. The electronics need the water cooling, and since the water's already required, they use it to cool the turbo itself as well. If they didn't need the coolant for the electronics, I suspect they'd have stayed with oil cooling.
