MAC Syrup Lipstick

  If I could only use one MAC product for the rest of my life it'd be their Lustre lipstick in Syrup. It's one of the few lipsticks that I've used up and it's one of two lipsticks that I've repurchased. I'm onto my third tube and it's still one of my most used lip products.  
MAC describe Syrup as a cloudy pink. I'd call it a mauvey pink which on me is a shade darker than my normal lip color. If you have pigmented lips, Syrup is the perfect everyday lip color.
Lustre lipsticks have sheer to medium buildable coverage and a glossy finish. I find the luster formula to be moisturising enough that I don't need to use lip balm underneath (unless my lips are really dry, in which case I'd be using lip balm instead of lipstick) and I love the vanilla fragrance.  
Syrup is right up there with my all time favorite lipsticks, it's so easy to wear and the color is beautiful.     What's your favorite lipstick?
