There's a tradeoff that needs to be made between reliability versus cost and more mission objectives.

The main benefit of the unmanned missions is that it allows you to skimp on the reliability.

Two unmanned missions with a 50% success chance are much cheaper than one mission with with a 99% success chance. For manned missions you have to do the cost analysis differently.
