I dislike how soft Urban Decay shadows are. I have Uzi and I hate it because it shows up very inconsistent and the glitter goes everywhere except the eyes. I have Shattered and I love that color, gorgeous metallic blue-green. I also have Fishnet Deluxe shadow and it's nice, but I really regret paying $19 for it. I don't even like purple that much, and it was a waste because it's cool packaging, but the plastic always falls off the top which makes the image try to get out, lol. They're nice, but I prefer MAC's powder shadows a LOT more.
I do love their Primer Potion, though I do prefer MAC paints and shadesticks. I also love love love their cream shadows. They're like the consistency of MAC LiquidLast Liner, but much easier to remove and used as shadows, not just liner. They're all creamy and gorgeous, especially Asphyxia and Oilslick.
