What do you set your concealer/foundation with?

I’m having a dilemma.. a few years ago, I purchased the KVD contour kit. Of course one of the highlight shades ended up being my HG setting powder. I refuse to repurchase and have since been going through powders like crazy trying to find the best thing to set my makeup with.

I’m not so much looking for suggestions per se, just genuinely curious what everyone else uses. Laura Mercier? RCMA? Fenty? Hit me!
