Dalton was closest to Fleming's vision (and I like Dalton's portrayal, I like them all except Lazenby), but I can't really get behind that interpretation of Bond turning on the charm in the movies, it seems a little manufactured. What's more, I think writing a protagonist for a movie is different from writing a protagonist for a book, a lot of nuances can get lost in translation, which means some concepts get simplified. And the series, for all its pros, isn't known for having exceptionally complex characters, so some things have to be made more obvious (although the Moore era did take far too many liberties, just look at that jungle scene in Octopussy.)
