What is your favorite primer and why?

I want to know what your favorite primer is and why! I love the Porefessional from Benefit and I really want to know if you guys think there is a better one!

I hopped on the bandwagon and recently bought Farsali's "Unicorn Essence" primer and I'm hooked! Prior to that I used Smashbox's face primer and Kat Von D's 'Lock It' primer, but the Farsali one is far superior. Like when it's on my face, a hurricane could not make my makeup budge. LOL!

I love the new No Poreblem primer! I was all about the benefit porefessional until I discovered this and it's everything!
