Siege towers are judged better than ladders because they give attackers a stronger way onto the walls. A breach is still preferred, especially one opened by sapping, because the whole force can move through a common gap. Whatever the access method, the first unit onto the wall has to hold while more troops climb up behind it. The comparison links siege equipment to the problem of securing and reinforcing a foothold.

Siege towers, ladders, and sapping
A quick comparison ranks siege towers above ladders but still favours sapping or another concentrated breach, while the first troops onto the wall must hold until reinforcements arrive.
