The other eyelash curler I have is THE famed Shu Uemura Eyelash Curler $19. I find that I have to be careful with this because it does pinch me sometimes.
I really don't see a difference between the two. They can both give me a great natural curl when used right but they can also both give me 90 degree angled lashes if pressed down too hard or long. I love both because one's cute and the other one is so glamorous!
