I have some UD shadows and a ton of MAC, and honestly I prefer MAC any day! UD has some great colors, but most of them are heavy on the glitter and are a bit on the dry, crumbly side. The only UD colors I really like are Shattered, Paladium, and Pallor (the last 2 are disc.). IMO, Paladium is one of the most gorgeous shades of silvery lilac. I actually use to have Midnight Cowboy and got rid of it, because I couldn't deal with having the color's silver glitter falling onto my cheeks. Kind of messy.
