IF heavy loads are your intended use, yes. At close quarters it won't make much difference and I think the 1/9 is actually better for lighter loads. There are also many defensive rounds available under 70 grn. It might be argued that for hunting game larger than varmints, a larger caliber is really much better than 5.56.
