Lorac vs Urban Decay

So I've been a long-time user of Urban Decay Eyeshadow Primer Potion. I've been through an entire bottle of original and am now using Eden. BUT since I got my Lorac PRO palette, I've been using the primer that came with it, so today I decided to pit my UDPP against my Lorac PRO primer. To keep things fair, I used the original UDPP formula sample that came with my Naked 3. So I put on my primer and did my eyeshadow as usual. My makeup has been on since 8:30 am and has been through school, lunch out, a nap, and a party. I walked through my front door at 10:30pm, which is when I took these photos.
I applied the Urban Decay to MY left eyelid, so if you were looking at me it'd be on the right. One thing I noticed was that the Urban Decay took longer to dry than the Lorac. Overall I felt that my eyeshadow applied smoother and blended smoother over the Lorac. Now I didn't see too huge of a difference in lasting power between the 2, both eyes are looking pretty worn down. BUT they lasted really well considering what I did today and how long my makeup has been on, about 14 hours.

This is the eye with the UD (above), I didn't do any cleanup because I thought that would take away from the comparison.

And this is the Lorac

So overall if I was choosing one I think I'd go with the Lorac, just because my eyeshadow applied and blended smoother over it. I find the lasting power about equal between them.

Just for reference I thought I'd list the prices for you guys:

Full sized Lorac Behind the Scenes eye primer: $21 (.5 oz)

Full sized Urban Decay Eyeshadow Primer Potion: $20 (.37 oz)
