Sean Connery and Daniel Craig are my favorites, and Quantum of Solace is my favorite as well (it's the only one I've actually seen the whole thing of).
The Living Daylights is hands-down the best Bond movie. It's interesting to note that Timothy Dalton most closely fits Ian Fleming's description of Bond.
Goldeneye was the first Bond film I saw as a young lad, so I've always had a soft spot for it. As for the best Bond, Pierce Brosnan really is very good, but I think I have to give it to Sean Connery.
