The Martyrdom of Antipas

Gary answers a listener question about the supposed historical fact that Antipas (mentioned in Revelation 2:13) was martyred in the mid-90s AD under Domitian. If true, this would mean the book of Revelation was written after the destruction of the city and the temple in AD 70. Preterists maintain that the book was written during Nero's reign in the mid-60s AD. So which view is correct and why does it matter?
