Truth 2: "The GM and the players do dialog at each other until the situation is resolved" is a good system for handling social interactions. There's no system that's overall better than this. (This is usually what people are actually debating when they talk about "system matters").
(Possibly true and deliciously controversial: Many systems that mechanize social interactions are made for players who fail at the freeform system. They are more like "crutches" than "fancy runners". Crutches are great if you can't walk without them but they won't help you if you are a decent runner already.)
