What is the most persuasive view of the literary relationships, or lack thereof, among the Synoptic Gospels, and what is at stake in the search for a solution to the Synoptic Problem?

A synopsis, which prints parallel texts from the Gospels in parallel columns, may be helpful: Aland, Kurt, ed. Synopsis of the Four Gospels (Greek/English; Stuttgart: Deutsche Bibelgesellschaft, 1994). This resource may be found at the Bodleian and Theology Faculty libraries.

Note: Mark Goodacre, who does not find the theory of Q persuasive, has a comprehensive website of sources for studying Q: http://www.ntgateway.com/synoptic-problem-and-q/websites/, as well as several excellent podcasts that introduce the debate: http://podacre.blogspot.co.uk/search/label/Q
