Groundwork bites the dust

I have decided that I will no longer be using MAC's Painpot in Groundwork anymore. I bought it initially to be used as a primer for my eyeshadows, but it just washes out the color and makes it look dull. I got a bottle of UDPP and that really works well. Here is a picture:
The top is with UDPP and the bottom swatch is with Groundwork. The purple is so much more vibrant with UDPP. Groundwork going to go to my makeup graveyard...second thought,I will put it on Makeupalley (glossyxlipz). I just have no other use for it.
