I have used MAC Paints, MAC Paint Pots, and MAC Shadesticks from MAC and I have also used Urban Decay Primer Potion. My favorite are the Paints and Paint Pots. The Shadesticks are nice but move after a few hours. I like UDPP but I hate the bottle. It's so cheap. I bought a full size one and dropped it after using it once and the whole base broke off, letting all the makeup be tainted and flow out. It sucked.
My mother has used Prep + Prime Eye, which she hated, and Cream Colour Bases too, which she also disliked. She prefers Paint Pots these days.
