In my opinion it is Connery then everyone else. So with that being said, out of the actors that have come since I am going with George Lazenby. Lazenby is probably the least popular Bond of them all but I feel that is unfair considering his one film is one of the greatest of the series - On Her Majesty's Secret Service.
If you take the best parts of Lazenby, Moore, Dalton, Brosnan and Craig you get the Bond Ian Fleming created. I find it funny that the actor Fleming wanted to portray Bond was David Niven who, in my opinion, is closer to Alfred Pennyworth than to the Bond-esque Bruce Wayne.
