I'll throw some more confusion on the fire.....
As to dies, I have had them all in both rifle and pistol and my preference is the Redding for general use, precision grade. RCBS is fine if your just loading and shooting or even hunting, but not all that serious. Lyman is ok as well. Hornady as mentioned is a pain but has some nice features if you can get around the negatives.
Now, if I want a set of really nice dies and I only have one set, and that's for 6.5 Creedmoor, I would go this with Whidden:

You can get them with or without bushings, your choice.
Finally, reloading is a sum of a lot of parts, each adding a small piece to the ultimate outcome. Some things you can skimp on and the add is miniscule, others make a much bigger difference.
I like the Lyman M dies for setting the neck size vs the full length resizing one step does all. I take the de-primer out along with the neck expander and do those in separate operations with a rcbs de-primer and the M die. I feel I get much better consistency that way.
Brass prep is another area where little things add up and you can pick and choose which you want to throw in. Again, most won't make a big difference but will add up.
And lastly, it's about you and your finger, assuming your gun and optics are all up to snuff.
Good luck!
