From what I can tell, its more towards the XR5/6 than towards the Edge/Rebel. Their allround kite (the sculp) has a fairly grunty bar pressure - so I suspect this will be higher bar pressure than the Edge and Rebel.
That said, it depends on what you want out of it. If you are interested in a old school/airstyle then I doubt you would be disappointed. If you want strong loops or to do unhooked stuff then the Orbit seems to be the one to look at (or even look towards the 3 strut segment).
As always, its nice to demo if you can but equally some kites need a couple of sessions to really reveal their character to work out if the pros outweigh the cons. I personally like the Duotone Rebel.
