I'm also on board with TND as Brosnan's best. Overall I think GE is the better made movie, but I think Brosnan was more convincing (and seemed to have more fun) in TND. TND is missing character development, but the movie on the whole, is Brosnan's most entertaining Bond movie.
I also think TND is Brosnan's best, and one of the most entertaining Bonds in a long time when it came out. Sure, Goldeneye was a good film too, but I disliked that nearly every scene ended with some sort of explosion. It was overkill, IMO. The last two Brosnan films have always been disappointments for me.
As for Dalton, I thought (and still think) Living Daylights was one of the best in the entire series, but that LTK was a disappointment. I saw LTK again very recently, and my wife - who is a Bond fan in her own right and quite knowledgeable too - said it seemed like a generic '80s revenge thriller, the sort which would have starred Jean-Claude Van Damme or Steven Seagal. Given the popularity of those actors in the late 80s, that angle must have come up in production discussions.
