Bentley Continental GT Vs. Aston Martin Vanquish

If you had to choose between a 2012 Aston Martin Vanquish and a 2012 Bentley Continental GT which would you choose.

Aston Martin is known as the "James Bond Car", but with the new book Carte Blanche James Bond has switched over to the equally impressive Bentley Continental GT. I can't choose which I like the most! So you have to do it for me!
