From my recent experience on a real project DDD inspires very rigid thinking sometimes on the boundary of being religious (e.g. the quest for pure Values and Aggregates eclipsing the problem domain understanding).

And for a regular "aggregate" entity I would never prefer a JSON storage to a data mapper with SQL (as long as you have an option to use SQL). You should have a reason for JSON and such, otherwise it's just NoSQL hype.
