I have both the Puig and Vstream N20123 (tallest) screens. The Vstream goes on in our cold and wet winters, the Puig in the summer. The taller Vstream provides significantly better protection than the Puig. So much so that it's too hot to sit behind in the summer heat, hence the Puig goes on.
As for the little clip on visor suggestion, I have one of those too and use it on both the Puig and Vstream. It gives me that last little bit of adjustability I like. I wouldn't get the Puig version, though. Knock-offs are available on eBay for <$20. I've had both Puig and knock-off and they are pretty much identical in quality and function.
