This issue can be resolved using basic Physics knowledge.
ST uses high amount of chakra and spreads it over a huge area (i.e. a village). A village poses no real resistance to it's power and is effortlessly wiped out. Now apply that same chakra on a smaller object (i.e. the Yang Kurama) but using the same way of spreading the power and you get a significantly weaker result.
The staff on the other hand focuses all it's power at 1 point - the end of the staff. It can be used to focuse all the energy or whatever on smaller and bigger objects alike (i.e. the whole of Kurama. Note: he only hit a small part of the body but the force was enough to move him away from the fillage).
Now the question: Is the Staff>ST? I wouldn't hastily label it stronger or better simply because it is a transformation jutsu. It could destroy a village 1 household at a time but it cannot match the blitzkrieg effect of the ST. And the devastation, caused by ST is mindboggling. So yes the Staff could theoretically destroy a village but is in no way superior to the ST.
But that is only my humble opinion.
