My question is, which will be faster and/or easier to work with: XML or JSON?

    According to Sam Soffes, TouchJSON outperforms XML property lists:

    When I was preparing for my talk I decided to do some benchmarks to show how much more awesome plists were than JSON. The plist version was about 8 times faster than my JSON Framework version. I was pretty happy with that result. My friend, Jake, said he was using TouchJSON to parse JSON in his apps, so I figured I’d go ahead and benchmark that one too. I was expecting JSON Framework to beat it because the interface to the JSON Framework is a lot simpler than the interface to TouchJSON.

    What I found was very surprising. TouchJSON actually beat plists. It was slightly faster in every test I ran. This is awesome because plists have a much larger file size. They are usually about twice as big as JSON files due to all of the extra markup.

    However, that is a single data point.
