No difference.

#### Explanation:

In a reactive circuit which consists of Resistance, Inductance and Capacitance there is net lead or lag between the applied voltage of frequency $\omega$ and the total current flowing in the circuit.

If one recalls the common mnemonic CIVIL,
one can remember that
In a capacitor (C) the current (I) leads voltage (V), voltage (V) leads current (I) in an inductor (L)

As given in the diagram, if $\theta$ is the angle between the Real and Apparent powers, then
$P = S . \cos \theta$
For the same angle $\theta$ and same Real Power either in the Lagging Power factor or in the Leading power factor case, Apparent power is same. As such neither is better than the other.
