Face Primers: Smashbox vs. Benefit

I'll admit that I'm new to the world of face primers, and I'll also admit that I'm no expert on make-up or skin care.  With that being said, I want to share a couple of products I've been using and how they've been working for me. 

I got the Smashbox primer as a sample at Sephora a while back.  I later found the Benefit POREfessional primer at Ulta and decided to try it to see which product I liked better. 

First up is Smashbox Photo Finish Foundation Primer:

This clear, silky product may seem like it's going to be greasy, but it's really not.  It feels so light on my skin that I can't even tell it's there.  It was easy to apply and felt very lightweight.  Also, my make-up stays in place all day.  It is on the pricy side, which is a major downfall for me.

Next up is Benefit The POREfessional Face Primer:

This primer, while it still feels silky, almost has a look of a BB cream or tinted moisturizer.  It also felt super light and was easy to apply.  It blends well and was long lasting.  This primer is slightly cheaper than Smashbox. 

The result: 

With both products, a little goes a long way.  I used about a pea size amount each application.  I'm no stranger to Benefit products. I use several of their products and love them.  This was my first product to try from Smashbox.  Overall, I love them both.  I'll probably stick with Benefit due to it being slightly cheaper and because I love Benefit products in general. 

Do you use a face primer?  What product do you use?
