I've never tried MAC E/S (Am I the only one?) but I like to pretend this is MAC for me. LOL. I tried this in Showy 224 and I was not disappointed. The pigmentation was great. I love the turquoise side of it, nice and shimmery, very blendable. The navy blue side is super pigmented (a little goes a long way) but it's matte and I had a harder time blending it out. But I loved it over all. I want to try the other colors. I got lots of compliments on this too which is always a plus!
