The syntax is not necessarily nicer, it has only a few changes in the lexical structure and the syntactic structure is pretty much the same. If it's a little nicer for a human writing it, it's a little hairier for a parser to parse it.
But how much you spend time writing JSON anyway? Most of the time JSON is read and written by tools. Human intervention is rare.
In addition to that, the native JSON parsers in the browsers are probably implemented in native code, and this parser of yours is written in JavaScript. So it wouldn't be a surprise if this was an order of magnitude slower than a native JSON parser.
