Amalgam is worse for cracking teeth. The thermal expansion coefficient of Amalgam is designed to be similar to that of natural teeth. The problem is the thermal diffusion coefficient. Or in layman's terms because it's a metal it conducts heat really fast and thus expands faster than your own teeth when in contact with heat, say a hot coffee.
