A few points of similarity - you will get excellent service from both companies, and chances are be very happy with the products either way. That being said, having recently become an Axiom owner (official story and review posts in the coming days) I would strongly recommend Axiom. Their approach to speaker design and evaluation strikes me as being more scientifically based than Aperion (no offense to them), they have much greater value when you compare similar models (even if you concede that the speakers are identical in sound quality - the cost alone wins the day), and they have a much longer pedigree as well (which may or may not make a difference to you). In terms of sound quality, others will come and comment on the "brightness" or "harshness" critiques, but I will simply say the sound is beautiful and I love it.
