In theory that is true...in reality the Merlin's seem to work better/more reliably. And the high altitude performance was less troubling - that was probably just the superchargers used but...in the real war that they were fighting the Merlin always seemed to work better than the Allison.
That was indeed just the turbochargers used. The Merlin had a less advanced, less complicated, more reliable, more pilot friendly mechanical supercharger. Both engines were ok.
