Depends on how you want to count things. Elimination of the human cargo means that more instrumentation can be flown, which means a potential increase in the amount data and knowledge accumulated.

It would be extremely difficult for a human crew to remain healthy and sane if put in space for 12 years (radiation, no gravity, claustrophobia), and it would conusme a huge amount of resources.

long term missions and/or one-way missions (like the probes that keep on going and going and...) that would be impossible or unpopular with manned missions.
