In my very humble opinion, i think that the graffitis of argentina have the biggest impact in the society between argentina, honduras and brazil (the link for see the colombian graffiti's was broken), because the government allow this type of expression and the society like see this graffities and what they have to say, due they can see the society problems from a different point of view.
I personally like the graffities and how the different artists show our world with different techniques and proportions that we can not see in other place, i am not sure if is the proportions of the painting or the difficulty that i know that is do something so beautiful in places so hard to work.
