HELP!!Which mascara works better: Rimmel y Curves or Maybelline Define A Lash?

I have 3 tubes of the Maybelline y curves mascara, 2 in black and one in waterproof black that i just bought for when i go on vacation next month, i loooooove it, it's great, i have tried other more expensive mascara's in the past that have claimed to make your eyelashes appear fuller and longer, but none of them have workd like y curves, plus the brush is designed differently to any other mascara wand so it doesn't clog up and get all messy and clumpy and doesn't get too much product on your eyelashes either, just this morning my mum said to me "Why do your eyelashes look soooo long?!" and i told her about the mascara i used and she said she wanted to try it which she did and she even loved it even though she doesn't usually care for mascara's, even the shiny tube is super cute, i would definatly reccomend the Maybelline y curves, even my friend who is a proffessional make-up artist loves it and uses it on herself and her clients and some of the clients are celebs but some are just models too.
