All things being equal(which they ain't) a trim die relies on literal outside forces,to curtail length. Such things will skew concentricity and neck tension,as well as mar projectiles.

A rotary trimmer does not on the average,though they are not all equals. In fairness,the worst rotary,easily trumps the best trim die.
