Answer

The BP of H$_2$O is 100C and the BP of H$_2$S is -60C. H$_2$O clearly has the stronger intermolecular forces.

Work Step by Step

Both molecules are polar, so they have dipole-dipole attractions. H$_2$S is not capable of hydrogen bonding, resulting in the great disparity between the two values.
