I took the time to do some research on this subject some 6 years back.
My answer was the RCBS Universal hand tool.
No swapping shell holders, it holds everything from .32acp to .444marlin.
My only complaint for years was I had to switch parts betweeen large and small primers. Until I got lucky and found a good used one for sale here. Now I have 2, my first which does large (and has all the parts)
And my second which does small and is missing a couple of parts but only cost me half.
So now I am truly happy. I can load primers in a tray, pick up a batch of mixed brass from the range, and prime and sort them as I go.
No switching nuttin but brass.
And I have learned that just a little smear of sizing lube on the main shaft keeps all actions smooth and easy.
I like the fact that I can tell by feel when a primer is seated correctly.
Your mileage may vary but that is what works for me.
