I've never ridden Fat-ypus skis before, but I do know that Halo 2's and Al Dentes are both insanely buttery skis. If price doesn't matter to you, the question to ask yourself would be do I want the wider ski (Al Dente) or the skinnier ski (Halo 2). Other than that I think the rocker and camber between the two are pretty similar. Both are durable as well, have friends that rock both of them and they love them.
