The reason I prefer JSON over XML is the latter's ambiguity. It's completely obvious how to convert a native object into a JSON object, for example. The translation to XML brings all sorts of questions about when to use tags vs. attributes of tags. It's cognitive load I'd rather spend on solving the problem at hand, not serialization. If there had been an opinionated SGML syntax which mapped directly and unambiguously to common language primitives and back, I'm sure it would have been more popular than JSON.
