Compared to an expendable mission, how does choosing a drone ship landing affect payload mass delivery?

Answer

It allows for a payload mass ($M_{DroneShip}$) only slightly less than the expendable mass ($M_{exp}$).

The trade-off shows that while an offshore landing incurs a penalty, it is significantly less severe than the penalty of dropping the stage entirely, allowing for a much higher payload mass than an RTLS attempt.
