I don't think there is any real advantage. To me it seems to be more of a preference and perception issue.
Proponents of striker fired handguns argue that the consistency of the trigger pull is an advantage, but I am not really sure about that. If you want consistent trigger pull from a hammer fired gun, cock the hammer. If you are in a situation where there is no time to do so, the adrenaline going through your system is likely going to make the longer stiffer trigger pull of the double action setting moot anyway.
As far as reliability and durability, There are plenty of examples of guns of both types that have thousands of rounds through them with no problems, and plenty of examples of both types that have crapped out way before that. My impression is that this is a maintenance issue. If you take care of of your guns, they will take care of you, regardless of whether they have strikers or hammers.
