Eyeshadow Primers....HELP!

Kay so I never have used eyeshadow primer. :O Shocking! I know! I don't have crease-less eyelids at all by any means, but I just figured I didn't really need the darn thing. Folks... I caved. Now the question is: Is there any primers that out do the rest? I've seen mixed reviews and to be honest I don't really like watching videos. SO my question is Urban Decay Primer Potion, Two Faced Shadow Insurance, Makeup Forever Aqua Cream, or Mac Paint Pots?!?! So many to choose from and I really love love love all the brands, but I can't make up my mind which one I should buy. Take note that I wouldn't be using this primarily for me, but I'll have to buy another one for my makeup kit to work on clients. Let me know your thoughts PLEASE!!!
