Yes, the staff is mightier than the sword... A good, well-built staff can also double as a tool, being used to pry open doors and locks, lift heavy objects, act as a handle for going down a zip-line, paddling a boat, fishing, and if a telescoping staff, being put away easily or made into a fun-sized melee weapon...
Seriously, can your beloved sword do that? I DON'T THINK SO...
