Straighter and softer. I don't notice a difference in flotation in fresh pow, but the tails want to hook up a tiny bit more. In crud I think the ANT is better. The JPs ski switch far better in my opinion though and are a little easier to deal with in the trees. The ANT has a slight edge on hardpack cause they have a tiny bit more sidecut.
I am trying to sell these skis, but to be honest, unless you are doing a lot of backcountry jumping and switch pow stuff you probably don't need both of these skis. However, if you are doing a lot of that stuff, the JPs kill it.
