I purchased the hornady a year ago. I've used the rcbs and have nothing against it. I got my hornady from cabelas used and was a little sceptical. The price was right and came with a warranty. Have to say after loading more then a thousand rounds that its fantastic. Very pleased with the accuracy of the charges thrown. I also have first hand experience with hornady customer service which is amazing and second to none in my mind.
I have read good reviews from both ,some negative with the Hornady , the Hornady is a lot cheaper . I will be getting one from Cabela's , still not sure witch one though .
