I have a discontinued 3x3 Rogue (the Fortis) I brought on closeout. The service was great, delivery reasonable, and when I callled about a very minor scratch they comped me without hesitation (they offered an exchange, but I already felt silly for complaining and just wanted to see what they'd do). I have also purchased two of their bars (the Ohio power bar and the Bella for my wife and kids), and a few other toys. I spent weeks going over comparisons with EliteFTS, and it came down to shipping cost, accessories, and delivery times (that and the closeout price I got).
I put it together with ease and drilled it into the concrete floor of my garage (I only used a single bolt on each leg rather than three each). It's very solid. I also installed the monkey bar and rings (I've used the rings more and more for pull-ups to allow wrist rotation), and the dip attachment, while heavy, is solid and pretty easy to put on and take off. The only difficulty was finding wrenches big enough to fit the bolts. I now have a couple of wrenches I could kill elephants with, but they weren't that expensive. It was a damned fine purchase and has served me well.
Edit to add: I agree that those are the two companies to choose from. I researched everything I could find before settling on those two. Basically, I doubt you'd be disappointed by either given the myriad positive reviews and positive reputations.
