Two completely different skis for different purposes.
The ANT is a fat, stiff, little sidecut ski made to, quote "point it and give'r". If you've paid any attention to how Boronowski rides, you'll know that's exactly what he does. It's long, it's fat, it has a tame amount of sidecut. It'll be easy to ski bigger lines in sketchier conditions with it, it'll do better at speed, and overall, it's just fucking gnarly.
The Maiden, also a great ski, is a little different. Tons of sidecut(comparatively), WAY softer, a little wider in the waist, definitely wider in the tip, it'll probably float you a little more, and will definitely be easier to ski. It's also a little better outside its natural environment of powder, and probably more fun in the park than the ANT, though Boronowski has no problems using his in the park when he so chooses. But then, you're not him, so ya.
Anyhow, you can't go wrong with either ski in regards to build quality, materials, etc, but you really have to ask yourself what you'd be doing with the skis. That's what it comes down to.
