well, you bumped, so I will reply.
I have NOT heard both. Hell, I have not heard even one of the systems. What I will say is that my M80s, VP-150 center, and QS-8 surrounds, paired with my BFD EQ'd SVS 16-46PCi really sounds incredible. The Axioms are better than any other speaker I have heard (that I could even come close to being able to afford). better than Paradigm (although I really liked them also), Klipsch Forte IIs, Boston Acoustics, EPIs, Pinnacles, Infinitys, and others. The SVS sub is, from what I hear, much better than the Axiom sub.
I got 15% off the price of my Axioms by buying a 5 pc. set from their online outlet, and they all look and perform perfectly.
Sorry I can't be of more help. I really like Atlantic Technology, and am a huge fan of pretty close to everything Peter Tribeman is associated with, but the Axioms are truly a fantastic system (with the SVS)
