The call

Isolate earns its premium for two specific buyers: the lactose-sensitive, and anyone chasing the leanest possible macros per scoop. For everyone else the difference is small, and the dollars-per-20g-protein number decides it — a well-priced concentrate routinely beats a marked-up isolate on everything but the lactose line. Both are complete, high-quality proteins that support hitting a daily protein target; neither is "healthier" in the abstract. Read the serving size on each and let the division talk. Taste preference (concentrate runs a touch richer) is reported as consensus, not a tested result.
