I have a smaller RCBS (RS5) that I started loading on in 1987, and I bought the predecessor to the newer designed Hornady (in a kit, just like you are looking at) for my brother. It's a fine press. I have the Hornady ProJector, the predecessor to the new L-N-L progressive, I love it.
The new presses all have the quick-change bushings, my only complaint on that would be it's just another component you have to buy. All our presses are old-style, and they don't slow me down in the least. I wouldn't make that the pivot in your buying decision. (What I did buy is the Hornady lock rings and the wrench that goes with them. The rings have machined flats on opposite sides, and you can spin them into the press and quickly snug them down with the wrench. Very handy...)
The one thing I would also say to watch is the scale. The Hornday kit used to come with a cheap digital scale, not a balance beam scale, but I think they changed it. No matter what, I would get an RCBS 5-0-5 scale, the RCBS kit comes with one already.
I believe the RCBS is a cast iron press (not sure on that) but the Hornady is alloy (which surprised me... my ProJector weighs a ton!) They are both burly presses and I don't think it matters which one you get... you ain't breaking them!
