What JSON library to use for data on iPhone

Question

There seem to be at least three different libraries for extracting JSON data from an HTTP request.

• TouchJSON ( http://code.google.com/p/touchcode/ )
• BSJSONAdditions (listed at json.org - http://blakeseely.com/blog/archives/2006/03/29/bsjsonadditions-12/
• json-framework ( http://code.google.com/p/json-framework/ )

For some reason, would I choose one of them over the other, or are they all about the same in terms of speed and least error?

The data I'm dealing with is likely to have some semi-complex JSON strings.
