Unfortunately I forgot to add my black eyeliner by Cover Girl, so I will review that one first.
Cover Girl's eyeliner does not need to be sharpened because you just twist the bottom and more product pops up when you are running low. It is not an amazing eyeliner, but it isn't horrible. It takes a bit of going back and forth on your waterline for the black color to really show up, and even then it's not the darkest black. But this is good to get the job done decently at a good price. If you wanted it blacker, I suggest using black shadow over it. It's pretty decent to use on the eyelid but again the color isn't so black, it's more like a dark gray to me.
L'Oreal's eyeliner is very dry as you can tell by the swatch above. Me no like-y lol
Kat Von D's eyeliner blew me out of the water. It is SOOOOO creamy!!! I could not believe how it glided on top of an eyelid when i want to rim the eye or make a cat eyeliner. I only use this one now for on top of the eyes. On the waterline is great but not the best.
Urban Decay's eyeliner I was not impressed with at all. I have to go back and forth on my waterline for the color to show up and I don't believe it lasts 24 hours at all.
MAC's eyeliner is hands down the best I've used on waterlines. The color intensity is definitely there and immediately shows. You don't have to keep going back and forth to get color. As for using it on eyelids, it is drier than Kat Von D's eyeliner and tugs a bit so I don't get as clean a line as I do with Kat Von D's eyeliner.
