Voltage has a meaning of a gain while voltage drop - of a loss; voltage is an earned voltage while voltage drop is a lost voltage. If we consider the voltage across an element, voltage means its own voltage (created by the element) while voltage drop means some else's voltage (created by an external source). So, in the first case, the element is active (a source) while in the second case, the element is passive (resistor, capacitor, inductor or something else).
