I love my 550. The only problem I had was I wore out the primer cup spring (not Dillons fault, I just load enough to wear it out!!!! 
) Dillion sent me new one at no charge :lol: . The 550 is also great if you are trying new loads because you can use it like a turret press and load one station at a time. I load all my handgun ammo on it. I don't shoot enough rifle to use it. I still use my Rock chucker for that. The Dillon customer service has been great. I have never used another machine so I can't compare. But then again I never had to use any other!!
