I've skied on Halos and I currently ski on the AR7. I love both skis, but the AR7 works better for me on big jumps and on bigger park features, the Halo however was a bit more playful. But at the same time spinning on to rails could become a bit sketchy because they are rockered and therefor you would preferably get them a bit longer than usual. I love both, but if you are planning on hitting bigger jumps you might want to get the AR7, easier to learn and get comfortable in the air on those.
