Why the Albacore struggled to replace Swordfish

What made the Albacore less successful than the Swordfish?

Its Taurus engine was less reliable, and it never offered enough improvement to overcome the Swordfish's proven reputation with crews.

The key contrast is between the Swordfish's reliable Pegasus engine and the Albacore's troublesome Taurus. Although the newer aircraft's engine problems were eventually improved, its initial reputation endured and the overall performance gain was not decisive. Crews trusted the Swordfish because it repeatedly brought them home, a confidence that mattered as much as modern appearance. That trust affected willingness to fly in dangerous conditions where a paper performance comparison mattered less than returning safely.
