UDPP vs TFSI

So, I've really been wanting to try Urban Decay's eyeshadow Primer Potion TRIED IT. But I've been reading reviews on Too Faced's Shadow Insurance, and it sounds pretty good as well. Some people swear by UDPP and some people swear by TFSI... so I'm thinking of trying TFSI later. For now, here's some great reviews to show you the pros and cons of each.
