I think it depends on your goals. My pistol ammo needs to shoot at least a 4 inch group at 50yards from the bench and I can match or exceed this easily with a good load on my Dillon 550B.
I have never found a powder dump that lives up to the consistency I want for my rifle ammo so all of it gets trickled on a balance beam scale. I just can not bring myself to trust the electronic scale when trickling powder. I have found the RCBS dump with the micrometer adjustment and a powder baffle to do the best among the major maker's powder dumps. I have never tried one of the really high end powder dumps so I cannot comment on them.
I would not trust the Dillon powder measure to give the consistency I want with any extruded powder or for any precision rifle ammo. About the most I would use it for would be .223 or .308 to be used for plinking or short range (<100yards) competition, and then only with a ball powder.
