Dior Foundation and Powder! Please help :)?

I'm gonna buy Dior DiorSkin Forever Extreme Wear Flawless Makeup SPF 25 & I don't know whether to just get the Dior DiorSkin Forever Compact Flawless & Moist Extreme Wear Makeup SPF 25 (the powder that comes with it) or Make-up Forever HD powder! I want something that sets my makeup for all day & just keep's it on! I can only get one, so which one would be best to get with the foundation? :) thanks
