Its not just about scratching dies, or good looks. The dirt in the case has primer residue as well and this gunk is Hydroscopic ( absorbs moisture) it also changes the capacity of the case slightly and gunk in the primer pocket / hole changes the ignition characteristics, these are all slight but they are variables and inconsistencies you dont want.
If two minutes of arc or greater is OK and you buy a new rifle every couple of years do nothing.
If you are trying to get the best out of your gun, then removing variations has to help you get there. Remember factory ammo is a new clean case every time and in many cases today will shoot as good or nearly as good as homeloads, so if you get sloppy in preparation, you may as well get factory ammmo.
+1 on the dawn and vinegar and water, works fine, dry them and tumble in corn cob finishes the job off.
