Its a matter of preference.. if you can compromise on crystal clear screen and clarity of ipad.. Powersupport AG is the best option for u, but some people like me dont mind wiping the screen once or twice a day.. but cannot compromise on the screen quality with a semi-blurry screen... Hence the crystal screen. I have a portenzo book case.. hence less finger prints... And PS crystal screen, Hence i dont have to wipe the screen more than one or two times a day.
