Urban Decay 24/7 or Make Up For Ever Aqua Eyes?

I am a hardcore Urban Decay junkie, my heart says 24/7 liners, but my head says MUFE Aqua Eyes. 24/7 liners definitely smudge. They don't last on the waterline at all. If you are using it for the upper lash line, then the choice is yours, but if you want something that will last no matter where you put it, go with MUFE.
