The best possible combo for 1:1 copies is
Clone CD and
Clony XXL
But this is of course hardware dependent.
I won't put down what settings I use as there a numerous copy protection which each need different settings - that's where Clony XXL will help you out.
Then you have to take into account your drive's capabilities - is it a no, one, or two sheep writer. This affects your decision of turning AWS on or off, or using such proggies such as Betablocker (although using AWS or Betablocker aren't strictly "perfect 1:1 copies")
