I like the line a lot. It is a little expensive, but then it's 25 scents, and the samples have the nice "logo", which, regrettably, is not printed also on the actual bottles. So I'd say that if you don't have access to a store selling them, it's worth it. If you have access to a place selling them (here in the US, pretty much only Henri Bendel in NYC and a couple of others), you can go and spray yourself there.
In terms of juice quantity, the prestige coffret, which contains 10ml bottles, is better. But regrettably it only has the first 16 scents, not the whole 25, so it excludes interesting things like Tom of Finland. (I bought the prestige coffret. But then I also go to NYC relatively often).
