Quick Charge 2.0 and Quick Charge 3.0

Has anyone on here noticed much difference between the two technologies?

Quick Charge 3.0 is so much better. The speed of charging is amazing.

as you would assume, the 3.0 is better. if you device supports it, then it will be way better

I think Quick Charge 3.0 is much faster, I want to get a quick charge.
