Not a direct answer but: I have nice vintage racing pedals and newer mid-level pedals, and I really don't see the difference. I've repacked the older hi-end pedals, they run smooth but hardly something to drool over. I ditched clipless for cages a few years a ago, don't miss clipless at all.
But...truth is, Powergrips (straps) are my favorites for road bikes and I'm fine with their stock performance pedals, which look like MKS knock-offs. Not an elegant or popular choice, but they work damn well - especially with the flexibility of positioning your foot inboard or outboard, deep or shallow, while riding.
So, just saying.
