Crowdsourcing Vs ARG?

The mission: real world, real life situations that need complex problem solving. A tonne of data is coming in through multiple mediums, clues a plenty, some relevant, others red herrings, sorting the dross from the gold needs knowledge, understanding and quick results before the data gets lost in the confusion of time.
Which is the best approach. CrowdSourcing or ARG and why?
Crowdsourcing is a neologism for the act of taking a task traditionally performed by an employee or contractor, and outsourcing it to an undefined, generally large group of people or community in the form of an open call. For example, the public may be invited to develop a new technology, carry out a design task (also known as community-based design[1] and distributed participatory design), refine or carry out the steps of an algorithm (see Human-based computation), or help capture, systematize or analyze large amounts of data (see also citizen science).
An alternate reality game, also known as an altered reality game (ARG), is an interactive narrative that uses the real world as a platform, often involving multiple media and game elements, to tell a story that may be affected by participants' ideas or actions.
The form is defined by intense player involvement with a story that takes place in real-time and evolves according to participants' responses, and characters that are actively controlled by the game's designers, as opposed to being controlled by artificial intelligence as in a computer or console video game. Players interact directly with characters in the game, solve plot-based challenges and puzzles, and often work together with a community to analyze the story and coordinate real-life and online activities. ARGs generally use multimedia, such as telephones, email and mail but rely on the Internet as the central binding medium.
