Revlon VS. ZA

Out of boredom and curiosity (and, doubtless, procrastination), I just tried on my Revlon New Complexion Oil-Free Wet & Dry Compact Make Up in Ivory Beige on the left side of my face and my ZA two-way foundation powder refill (number 22) on the right side. The Revlon is a bit whiter than my real skin while the ZA comes up slightly darker, almost orange-tan. As for coverage, I think the ZA hides my redness better. Maybe they can be used in conjunction to get the right colour? Maybe I can use the MM Pressed Pore Cover or the Mistine BB loose powder or the Boots Natural Collection Illuminating Loose Powder on top of the ZA. Or maybe I'll give the ZA away. If not, how do I make it fit into my MM case(s)?

So I guess that's a draw.
