The Avalons require megawatts of power -- and they are way overpriced compared to other speakers that are just flat out better. The Avalons also don't have the best dynamics. I think a lot of people buy them for their cabinet work and their looks in general.
If you're after cost-effective performance, the Vandersteens are hard to beat. And while they may be forgiving, they're also highly capable of revealing differences in upstream components. Also, the Vandersteens are phase- and time-coherent. The Avalons (and ProAcs) are not. This may not be a big deal to some people, but it's been my experience that phase- and time-coherent speakers do a better job of imaging and recreating the illusion of a live event. They just sound more natural.
But, hey, there are lots of great speakers out there. Listen to as many as you can. IMHO.
