Obviously around here you are going to get you should buy the Axioms, but the Aperions look to be a good speaker as well. I am not overly optimistic about the waveform it has, there is quite the bump in the 50-60hz range and then a drop and then another increase in the very upper end, which I don't think would really affect much as very little is played up in that range.
As was mentioned and it seems you are willing to do, buy both and go with the ones you like best. You may want to buy just the towers first as it would be much cheaper to ship only the one set back.
Have you looked at the hearing things forum to see if there is anyone around you that could give you an audition of some Axioms? If there is no one nearby then send Amie a PM as she might be able to contact someone for you.
Good luck
