I think these pictures are pretty good because the car is in a variety of lighting conditions. Though, there aren't any that are more overcast but still in the sun.
I certainly wouldn't call Zaino "plasticy". And I wouldn't say it lacks depth (though Souveran certainly has a bit more). I think the car looks great! Compared to Blackfire, it seems to have more shine/reflection and a bit less of the metallic pop. However, the metallic pop that it has (and it definitely has some) is a bit more natural looking than the Blackfire pop.
However, Blackfire has a lot of reflection too, and the metallic look is really cool. I enjoy the way both of them look, and the difference really isn't all that large.
To a very large extent, it's the paint that has the depth, pop, and shine. The protectants just tweak it a bit to get different emphases. I like the look Zaino has, and I also like the Blackfire look. And of course, I love the Aurora look!

I look forward to seeing the Z a bit more, seeing how it behaves over time, in rain, and so on. These will probably be the aspects that determine if I stick with Zaino, or go back to Blackfire (or go for a combo). They both look pretty awesome. I also look forward to trying the Z2, which I haven't used yet.
If I were recommending it to someone, cost would be a factor too, but of course, I already bought it all. Blackfire really only requires the protectant (I don't use the polish anymore, and you really don't need the shampoo/QD), plus there's a chance you can get it on sale. Z2/5/6/7/FX is like $80, and the only deal is maybe a free applicator... For $80, I could buy Blackfire protectant, a gallon of Final Detail, some Swirl Free Polish (which I'd need with the Z too) and probably a bunch of bottles of #00 car wash. Though the Z6 really did impress me. It's a very nice QD, but then Final Detail really impresses me too.
I think I could get the same number of applications from the two 8 oz. Z's as from the one 16 oz. BF because they both go on equally thin (thin enough I can't imagine ever buying either again!). Plus, I've never had to pour BF out, though I also can't slap on 3 coats in one day. Pouring out almost as much Z5 as I poured from the container made me

And of course BF's prep is easier. I put it on right after the Swirl Free Polish, buff, and that's that.
So in summary, is Z super awesome incredible that makes everything else crap? No way! Is it a really great looking product that I'm glad I tried? Heck yeah!! Do I look forward to more time with the Z? Oh yeah!
Edit: I hope this doesn't read wrong. I really think the Zaino is great stuff. It's just that I was already using great stuff. But it's only been a week, and the car's been in the garage most of that time (where I noticed whenever I went out there that it had more reflection). So there's still time for me to get blown away. :wavey
