It definitely matters. What are you trying to accomplish? Bump shoulder, full size, just neck size, then what features which other guys already covered.
Stuff to think about though:
Adjusting neck tension = bushing dies
Micrometer for fine tuning seating depth (makes it easier IMO).
Gas gun full size die
Neck size works brass less(better brass life when not annealing). Some think neck sizing is the devil but many have success with it when it comes to accuracy. Usually bolt just closes hard.
I am parting with my type s dies. I have a lot of issues bumping the shoulder with them. They just don’t move it at all and my bolt is very hard to close. I’ve had great luck with whidden standard dies (non bushing) for my dasher and will be switching to them for my 6.5cm also. Check whidden out they are priced well too!
