havent heard so much about the afterbangs in terms of the actual
skiing, but the features of them sound sick. skateboard deck kind of
build up, super light and very durable. i heard that they smacked them
against rails after soaking them for several hours in water and then
massively cooling them so they would freeze. but on the other hand they
are the first of their kind, so they are not as developed yet as skis
that were on the market for a longer time and therefore were constantly re improved.
maybe here about what others say about them once their are open for sale.
but the fact that they arent so expensive makes them very attractive.
havent heard so much about the moment skis, so i dont want to talk about things im not 100 % sure about.
maybe consider the alpha 1s, they look really ill and really progressive. the have a slight rocker too, for sick presses. a short radius for carves.
the ar6 would be more traditional but slightly stiff. i have it. its cool, holds an edge really well. has dope graphics, but is a little too stiff for my taste. i also dont like the fact that they arent symmetrical. but apart from that they also arent too bad in pow (for a park ski)
maybe consider the völkl wall or the atomic punx. the punx have a really nice top sheet and throw massive rooster tails 

 u see alot of pros riding these skis
anthem is fairly soft and wide, a good allmountain ski IMO.
hope i could help you out a little.
peace
