Is a MIPS helmet worth the extra money?

The consensus across the high-trust communities we read (r/cycling, r/bicycling) is that MIPS-equipped helmets at least carry the assurance of thorough testing, and many riders prefer them for the added rotational-impact protection. That said, some long-term owners report feeling no real-world difference, and reviewers stress that fit matters more than any single technology: a well-fitting non-MIPS helmet beats a poorly-fitting MIPS one.
