Are one-piece steel hammers better than fiberglass or wood handles?

One-piece forged steel hammers are widely praised in long-running specialist threads for near-indestructibility, with multiple owners reporting decades of service. The trade-off is shock transmission, several reviewers cite elbow and wrist fatigue with all-steel hammers. Wood (hickory) handles dampen shock best and are easy to replace if broken; fiberglass sits in the middle on both axes.
