A hand-squeezed crimp is only as good as the pressure you happen to apply, which is why home-built plug wires so often fail at the terminal. A ratcheting tool will not release until the crimp is fully formed, so every terminal comes out the same. Interchangeable jaws mean the same frame handles plug wire terminals and general automotive connectors.
