Here's my take...I have both. If you shoot cast bullets the Hornady is THE way to go. You get an extra die station that allows you to have both a powder cop die and a neck expander with a separate taper crimper. If you shoot only jacketed, there is no advantage to the extra station. That's point one. Point two, the Blue machine has a slightly less troublesome priming system. Just slightly. If you get sloppy with the Hornady and let any powder get spilled into the primer slide path it's jam city ahoy. The Blue machine is less susceptible to that issue. Score one for Blue. The Red machine is always auto advance. Learn how to use the machine and that's no sweat but....the learning curve is steep. Score one for Red and Blue. The shell keepers on the Blue machine are little studs that get lost, are hard to use with fat fingers and generally are a PITA. The Red machine uses a spring band..very simple to add or remove cartridges. Score one for the Red. The powder measure on the Red machine is minutely adjustable just as it comes from the box, the Blue machine needs some aftermarket stuff to make it easier to adjust and repeat. Score one for the Red. The Blue machine uses a strong mount to make it bench friendly, the Red machine needs a 1.5" overhang to make it fully swing on the bench. Score one for the Blue but...the strong mount costs more $$$. Both have a no BS warranty, score i each Blue and Red. The dies on a Hornady are cheaper and they have rapid change lugs so you can leave them adjusted and change dies quickly. Score two for the Red. The Red machine is cheaper and the bullet feed and case feed if you want them, are cheaper too.
That's my experience
