Extase Pinks is much prettier to me with its pinks, purple and two gorgeous grey/silver shades. I can see using the two grey/silver plus the light pink in the middle for a smoky look and also the two pinks and the purple for a nice bright pink/purple look. Overall if I could only get one, I would definitely pick this one up.
And finally, here are some pictures of my ever growing collection of Dior quints. I have 38 of them and can't wait to add the two new summer ones, Ready To Glow and Crush Glow.
