I say the following owning a Dillon 550. I think any of the three machines will do a great job and pump out an amazing amount of ammo. The one thing I will say about the Hornady is that the shell plates and the die quick locks can be bought most everywhere. With the Dillon you pretty much have to order the caliber conversion kit and tool head from Dillon or Brian Enos.
I bought the 550 because I prefer the manual index. That way if something happens during the cycle I can recover more easily. Also I did buy the 550 case feeder. It supposed to only do pistol, but I modified the cam plate so it could do rifle.
It comes down to this, do your research and try to figure out which one might suit you better. With either one I don't think you can make a bad decision.
I'd add one thing to this - Dillon parts and kits are available thru Dillon dealers too, some of which frequent gun shows and such. Also, used stuff on ebay, craiglist, etc is still covered under the no BS/lifetime warranty, but right now isn't cheaper on ebay than new from Dillon! Don't know much about the Hornady's. Dillon's a great co. with a great warranty and customer service. 'Course, Hornady's no slouch on CS either so far as I know. My 550 works well for me and, as mentioned above, is nice to be able to back up manually if you wish to change something. JMHO.
