I was recently gifted BeYu 209 and Max Factor Fantasy Fire by a dear sweet friend of mine - Kristy. If you don't know about her lemming-inducing blog, click here. You're welcome.
Here they are swatched at one, two and three coats.
Opacity: Clarins 230 is the sheerest needing at least three coats while the BeYu is most opaque--you could definitely get away with just two. Fantasy Fire is a little more opaque than 230 but also looks best at three coats.
Colour: Compared to 230, the BeYu is very red while Fantasy Fire is very blue.
Shimmer: 230 has the most duochrome shimmer followed by Fantasy Fire and then BeYu 209 which has the least.
Overall: I think they are all very pretty but 230 is still my sweet baby :)
