What is the advantage of this +20% quality and the base quality gem - Grayscale Photography of Bridge

I was searching on trade for a corrupted lvl 21 molten strike and decided to compare quality +20% to normal one, and as far as I can see, there is no difference between them (appart for the price 3 chaos for base quality vs 90 c orbs) Do you see or can point a difference between them?
