4 adds cool stuff like religion, which actually really works, and greatly expands upon a lot of aspects of 3. It does come with the sacrifice of those zany live-action advisors though, which to this day I honestly kinda miss .>_>; All told it's a better game.
5 greatly enhances combat, and visually it's kinda gorgeous, but it's lacking still in a couple of improvements that 4 made which makes declaring a superior game somewhat tough for me. New expansion for it pretty soon though, which will add back things like religion.
