The UN is clearly the better marketer, because it needs to work much harder to justify its ongoing "good" for the world.
I wonder if FIFA has ever been discovered to be running hugely corrupt wings like UN's WIPA which keeps trying to stuff some form of ACTA/SOPA/PIPA down our throats.
I wonder if FIFA has been found to ever profit from the rape and sexual abuse of minors. Minors, who descend from some of the most war-torn and horrific places on Earth.
7 billion annually and look how little they get done each year. Capitalism is much more responsible for Africa's and Asia's escape from poverty than the UN is - and that's a rather low bar.
I laugh at the idea that the UN, and not the charities they force to go through them, is responsible for saving 2 million lives per year. I wonder how many millions they let die each year.
In terms of global politics, FIFA is rather benevolent and yet they foster ongoing positive international relations benefits. The UN is, at best, malevolent, and I am dubious that their positives outweigh their enormous negatives, not to mention their negative externalities.
