Lazenby got screwed, because in her majesty's sercret service bond got married and then his wife got killed. What a horrid ending? It definitley soured the whole movie and my view of lazenby (even though not his fault). I don't really like moore either.
In some of Moore's later movies he was and looked way too old, it was ridiculous.
Pirce and Sean are my favourites, although more recent bond movies haven't been that great. Dalton was probably too serious for the role, but he still did a pretty good job. Moore just looked like a crusty old dude in some of his roles and lazenby didn't really get a good job of proving him self. ALthough he was an Aussie so i have respect for that
