In few words: yes. Installing ball diffs rather than plaing gear diffs gives you the availability of choosing the diff adjustment.
Lets see a low traction surface (by example: polished wood) when a tyre slips with gear diffs, all the traction goes to the slipping wheel. With ball diffs you can adjust tighter to limit those pesky effect.
Think that a ball diff is like an LSD diff with fixed adjustment. The behaviour of the diff is changed tightening or loosening it.
