I've flown into the Honduran and Brazilian airports on that list. The one in Quito is worse IMO. There's a reason that Latin American passengers literally applaud when a plan successfully lands there. It will give you religion.
Also, when you get off the plane in Quito, you're greeted by an awesome poster of two soldiers with dogs that says "Please don't bring drugs into Ecuador." I think it's the politeness that really hits home with me.
