They're both about the same price. Which one should I get? I heard these two make it look as though you have falsies on, but which is generally better? Thanks!

Definitely go with Benefit's Bad Gal Lash - it gives you thick, long lashes because there's microfibers in the formula that bond to your existing lashes.

You could also try (if you want super length) Fast Lash by Tweezerman - you coat the lashes with mascara, then add the Fast Lash, and then again coat with mascara. CRAZY long lashes!
