Viburnum Robustum vs. Chino Sweet Viburnum

The local nursery has Robustum so I've seen it. I have not seen the Chino in person, but since it's taller that's a plus.

Need an evergreen variety that is tall and dense enough to make a privacy screen. Zone 9, full sun, drip irrigation. I know Robustum will do it. Since I have never seen the Chino, I'm hesitant to just go with that. Pros and cons of either variety???

Should I take it as a sign that since the nursery has Robustum that it is the one that grows best here and forget the Chino?
