I had the Zero Gravity Corsa but I found it to be too tall for my liking... Now I have the Puig Race Clear (2mm) and love it! Both are pretty awesome to be honest but I prefer the profile of the Puig.
As for the tinted screen, I had one on another bike and could never get used to it. Yes you can see through it but there's no way it's the same. Every now and then I'd get a cloudy day and I still had my dark visor on and it would get really hard to see. It was some generic brand that came with the bike but it has put me off tinted for good.
