Engineering teams rarely trifle over price of parts when reliability and confidence are greater concern. Sure, the neo2 is cheaper, and the rock64 is more powerful, but I haven't heard of either. What is the probability of encountering a weird not-before-seen bug on these platforms, vs Pi? Now what's the cost of dealing with that bug, including the risk-cost of having to scrap the entire platform because it's unscalable? It's probably at least $20x750 = $15k.

Pi has at least 10x more community eyes crawling over the whole system than the next three combined. You can't put a price tag on that.
