I have the VP100. It sound great in my 12x13x8 room and for the money I spent I have zero complaints. It replaced a Paradigm Monitor CC350. I had the chance to compare them side by side, and the Axiom was much better. I suppose if I never got the chance to compare the VP100 to anything else, I might be tempted to move up to the VP150, but there's enough of a difference in price that I really have no desire to trade up.
