Ok, so all three of the EDSF's finally arrived. I am in love with superb. It's much more metallic and the color is very soft so it's a gorgeous highlight. As for fairly precious and Magnetic appeal, they are less shimmery/metallic and are more pigmented. I knew when I ordered MA that it was going to be darker, but I wanted to try it as more of a blush. Fairly Precious however, I wanted to use as a highlight and I really can't. It just makes me look like I applied my blush way too high, and I look ridiculous. I think it will be nice to go over blushes, but I dunno, I'm still torn on this one.
I took several swatches to try to show to color differences. I took some inside and some outside. I hope these help anyone still trying to decide. I don't get my stuff till late, so it might be too late to help anyone but here goes anyway:
Top color, closest to my wrist: Fairly Precious
Middle color: Magnetic Appeal
bottom color: Superb
This last one is inside under fluorescent lighting, and although it's not flattering light I think it shows the tonal differences the best, as well as how much more metallic Superb is.
