I have tried many, many eyeliners in my day. I have a big problem with liners and shadows creasing (I'm half Asian and can get slightly oily lids as the day wears on) so when I use poor quality liners they end up smudging off halfway through the day. For a long time I used Lancome Le Stylo liner, which is nice and wears pretty well, but didn't go on the smoothest at times. MAC Powerpoint goes on like butter! It's very smooth to apply but sets up very quickly. When I use it with a good primer it stays put. I've fallen asleep with my makeup on and my liner barely budges at all. My absolute favorite color is Stubborn Brown, a deep rich espresso brown that's great for every day. I also have Powerpoint in Engraved (black) and I'm not as crazy about the color. It seems to have a blue-ish undertone to it instead of being a pure black. You definitely need to use a makeup remover or a good facial wash to get this liner off, but that's the point I guess. My only complaints are it's a liner that requires a manual sharpener and I always feel like I waste a lot of the liner by having to sharpen it to a point each time - I wish they had it in a mechanical pencil form. But it works so well I will stay pay for it!
