What's the difference?: NYX Matte Finish Setting Spray vs Urban Decay De Slick Oil-Control Makeup Setting Spray

So, I know I'm way late on posting this, but better late than never right? This is a comparison between two products that claim to do the same thing: keep your face looking matte. As someone with oily skin, I'm always on the lookout for a product that will reduce shine on my face. Here are my thoughts on the NYX Matte Finish Setting Spray and the Urban Decay De Slick Setting Spray:

What they look like:

As you can see, there is quite a big difference in the amount of product you get. NYX gives you 2.03 fl oz (60 mL). UD gives you 4 fl oz (118 mL). What you can't see in the picture is the big difference in price. The NYX setting spray retails for $7.99 on ulta.com, while the UD setting spray goes for $29.00. So, you get about half the product for way less than half the price.

I bought the NYX setting spray a few weeks ago, in the hope that it would be a dupe for the UD. This stuff has a fine, even mist, and you only need about three sprays. It smells really good and feels amazing on the skin. It does take a while to dry though, and the directions say to dab off the excess(which I don't). You spray this product on after makeup, but before powder. I did find that I didn't have to blot my face as much throughout the day, and when I did, there wasn't as much shine as usual. Overall, this product was a win for me.

I've had the UD for a while now. I bought the mini size initially just to see if I liked the product. Evidently I liked it so I bought the full size (this was a while ago, which is why the packaging looks different). You spray this on before AND after makeup. First as a base, then to seal the makeup. That part puts me off a bit because, not only are you using more product, but it takes time for the product to dry and sometimes I forget to do the second spray. So, if you are somewhat in a rush, this could cause an inconvenience for you. Also, I don't find that this makes a huge difference in the amount of shine on my face. I used it a lot in the summer because I would sweat more, and it felt very refreshing on the skin, but so far, I prefer the NYX setting spray over the UD.
