WebBond dipole moments also correspond to electronegativity differences so they will agree with each other. Personally I prefer using something called the Van Arkel–Ketelaar triangle for determining bond type. It's essentially a triangle which inputs electronegativity differences and averages from two bonding atoms and plots them in a 2D plane.
