my crimpers are the hex type which compress from all sides - does anyone know if this type with a single point of "squeeze" have any benefit, or tradeoffs?

I was told years ago that the goal was to maximise metal contact, reduce internal volume (compress the strands/cores) and essentially microweld the cable to the lug so it was difficult/impossible for corrosion to become an issue. I don;t know if this method is achieving those outcomes.
