I use the Dillon Super Swage 600. Very quick. On select match cases for long range precision loads I use the primer pocket profile reamer on my Wilson trimmer. Cutting has two advantages over swaging: One is that there is no anvil squashing any flash hole (also called the vent) burrs flat and over top of the vent itself (I usually deburr the inside of the vent on my drill press before swaging for that reason). The other is that the swager pushes brass aside, which results in a slightly raised area around the lip of the primer pocket. It will flatten back out at the next firing, but for precision loads I want it gone already.

Cutting also has one disadvantage compared to swaging tools: It is much slower and more effort to do. That's why only a small number of select cases get that treatment from me.
