Hornady L-N-L AP if you have a number of cartridges to load, and particularly if you need to switch large/small primer sizes. It is much easier to do caliber changes in the Hornady.
Funny, the Hornady vs. Dillon debate has been ongoing for many, many years, and I am seeing a lot of folks finally getting in the Hornady corner. I have had 2 of the L-N-Ls one for 10 years, the other about 7, now and have been totally pleased. The only problem, besides the case retaining springs which will twist and break eventually (easy and cheap to replace, or Hornady may just send you some) was when I tried to force a 9mm case one time and broke a pawl. Hornady had a new one to me within 24 hours. I was amazed.
If you plan to load rifle cartridges as well, I think the auto advance turret presses, like the Lee Classic or the Redding are a good option.
