Zinsco ain't ALL that terrible... at least phases can easily be switched on the back of the breakers. This is important because the acring that usually occurs on the busbars gets so bad you really need to use an adjoining phase.
Might be better off with the acring though... the arcing is probably more reliable to open the circuit breaker, than the mushy feeling OEM Zinsco breakers.
Why is it the AFTERMARKET Zinsco breakers seem to feel and work better than the OEM Zinsco breakers?
