Undeclared Haz is the biggest threat to freight carriers, IMHO.
A lithium fire in the cabin can be covered and doused with water. Since, presumably, everything going below is screened better on an pax airliner I give the lithium safety nod to Pax carriers.
If you don't want to carry lithium batteries you should not be flying freight.
