Morgan Freeman > Bruce Willis, so yeah, Deep Impact. generally I like drama over action, since drama is story-telling whereas action is just stuff that happens. My memory of both movies is hazy as I've only seen each movie once but I remember generally preferring Deep Impact, even though excitement-wise Armageddon better on that one aspect.
